     BACKGROUND OF THE INVENTION 
     1. Technical Field 
     The present invention relates in general to telecommunications and, in particular, to voice identification. Still more particularly, the present invention relates to initiating authentication of the identity of a callee at an origin device. 
     2. Description of the Related Art 
     Telephone service has created communication channels worldwide, and those channels continue to expand with the advent of cellular and other wireless services. A person can simply take a telephone off-hook and dial a destination number or press a send button and be connected to a telephone line around the world. 
     Today, the public switching telephone network (PSTN), wireless networks, and private networks telephone services are based on the identification of the wireless telephone or wireline that a calling party uses. Services are personalized according to wireless telephone or wireline telephone number, where service associated with one telephone number are not accessible for another telephone number assigned to the same subscriber. For example, there is typically a first set of service features and billing options assigned to a home line number, a second set of service features and billing options assigned to an office line number, and a third set of service features and billing options assigned to a cellular telephone number. The networks process calls to and from each of these different subscriber telephones based on a separate telephone number. 
     One of the services provided by many networks is caller identification. However, caller identification (caller ID) is limited to identification the wireline or wireless telephone number and the name of the subscriber of a service. Where multiple people share a single line, only the name of the person who establishes a service is displayed as the caller ID, often causing confusion about who is actually calling. 
     Caller ID is further limited in that it only flows from the calling party subscriber line to the called party. Multiple people may have access to a telephone device receiving a call, such that the calling party does not know now exactly who will answer a call. According to current caller ID systems, even if the caller ID where to flow back to the calling party, that caller ID would only indicate the name of the line subscriber to a phone number called by the calling party, and not the identity of the person answering the call. 
     In particular, while wireline telephone plans often bill a line subscriber at flat rate per month, wireless telephone plans often bill a line subscriber according to the minutes utilized per month. Where a wireless telephone is utilized to call a number that may be answered by multiple people, the wireless telephone caller must wait to see who answers, and thus be billed for the minutes, even if the person who the caller wants to speak with is not the person who answers. 
     Therefore, in view of the foregoing, it would be advantageous to provide a method, system, and program for providing an identification of the person answering a call to the calling party. In addition, it would be advantageous to provide a method, system, and program for providing an identification of the person answering a call to the calling party, such that the calling party may decide whether to speak to the person answering the call. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing, it is therefore an object of the present invention to provide an improved telecommunications system. 
     It is another object of the present invention to provide a method, system and program for improved voice identification. 
     It is yet another object of the present invention to provide a method, system and program for initiating authentication of the identity of a callee at an origin device. 
     According to one aspect of the present invention, at an origin device, a voice utterance of a callee is detected from a destination device. A callee identity associated with the voice utterance is identified at the origin device, such that the callee identity is transmittable as an authenticated identity of the callee for a call. A caller may select whether to continue a call dependent upon whether the callee identity is preferable. 
     According to another aspect of the present invention, an authenticated callee identity for a call is received at an intermediary device. A callee profile for the authenticated callee identity is retrieved. Then, a selection of services from among multiple services that are offered for the call are specified according to the callee profile. 
     All objects, features, and advantages of the present invention will become apparent in the following detailed written description.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     A method, system, and program for origin device initiated callee identification are provided. By authenticating a callee identity at an origin device, the caller may decide whether to continue a call or indicate the name of the desired callee. In particular, the identity of the actual callee who answers a call is detected by the origin device, rather than just the name of the subscriber of a wireline or wireless number. 
     One advantage of origin device initiated callee identification includes performing callee identity authentication without requiring use of intermediary network resources. Another advantage of origin device initiated callee identification includes maintaining an address book of voice samples of callees at the origin device, where the caller may choose to only continue calls with callees in the address book. In particular, the caller may also have more confidence in a callee identity authenticated at the origin device because the caller may independently verify and store the voice samples at the origin device. 
     Where needed, a third party server may be accessed by the origin device to aid in callee identity authentication. Authentication by a third party server allows the callee authenticated identity to be verified by an external source without use of intermediary network resources. In addition, a third party server may store voice samples independent of the origin devices, but in a trusted manner. Further, where a caller utilizes multiple origin calling devices throughout the day, the caller may choose to store an address book of voice samples at the third party device, where the third party device is accessible to the multiple origin calling devices. 
     While in the present invention, authentication of a callee identity is described with emphasis placed on voice authentication, other methods of callee identity authentication may also be performed. Voice samples utilized for voice authentication are just one of multiple types of biometric sampling. For example, a callee may locally provide an eye scan, a fingerprint, and other biophysical identifiers that are transmitted within or outside the trusted network to authenticate the identity of the callee. Alternatively, keypad entries, such as a pin code, credit card account number, password, or other secure transaction key may be entered by a callee and utilized to authenticate the identity of the callee. 
     In addition, while in the present invention, authentication of a callee identity is described with emphasis upon performing authentication at the beginning of a call, authentication of a callee identity may be performed continuously throughout a call, at selected points throughout a call, and after a call. Selected points where authentication may be performed include when an additional phone pick-up is detected, when a new voice is detected at the origin device, when a call is transferred from one telephone device to another, and other routing of a call that may result in a new callee or in a call being recorded. 
     For purposes of the present invention, telephony devices are termed origin devices when utilized for origination of a call to an intermediary device and are termed destination devices when utilized for receipt of a call from an intermediary device. Subscribers to a call are termed callers when originating a call and are termed callees when receiving a call. Callers and callees may or may not be line subscribers to the particular telephony device utilized. 
     For purposes of the present invention, telephony devices are termed origin devices when utilized for origination of a call to an intermediary device and are termed destination devices when utilized for receipt of a call from an intermediary device. Subscribers are termed callers when originating a call and are termed callees when receiving a call. 
     In the following description, for the purposes of explanation, numerous specific details are set forth to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form to avoid unnecessarily obscuring the present invention. 
     With reference now to the figures, and, in particular, with reference now to  FIG. 1 , there is depicted a block diagram of a network environment in which the present invention may be implemented. While the present invention is described with reference to one type of network environment, it will be understood by one with skill in the art that the present invention may be implemented in alternate types of network environments. 
     General Network Environment 
     First, the network environment incorporates a Public Switching Telephone Network (PSTN)  10 . As is known in the art the core of PSTN  10  may include multiple telephone networks, each owned by one of multiple independent service providers. Each telephone line is carried by an independent service provider within PSTN  10  and is typically assigned to at least one subscriber. 
     Switching of a call within an independent service provider&#39;s telephone network is considered trusted movement within a trusted network because the call remains within the company&#39;s telephone network infrastructure. However, calls may be transferred from one service provider&#39;s telephone network to another service provider&#39;s telephone network in generally trusted movement. Generally, service providers are in competition with one another and therefore there is general trust in transferring a call, but not trust in sharing of subscriber information beyond a subscriber number and name from one service provider to the next without security features or other arrangements. 
     Advantageously, each telephone network within PSTN  10  may access a data network functioning as an extension to PSTN  10  via an Intranet. Data networks may include, for example, subscriber profiles, billing information, and preferences that are utilized by a service provider to specialize services. Transfer of information between a service provider&#39;s data network and telephone network is trusted movement in sharing of information. 
     Further, each telephone network within PSTN  10  may access server systems external to PSTN  10  in the Internet Protocol over the Internet or an Intranet. Such external server systems may include an enterprise server, an Internet service provider (ISP), an access service provider (ASP), a personal computer, and other computing systems that are accessible via a network. In the present embodiment, transfer of information between PSTN  10  and server systems accessible via network  20  is totally untrusted and therefore may require authentication and additional security. 
     In the present invention, network  20  may comprise a private network, Intranet, or a public Internet Protocol network. Specifically, telco application server  22 , generic application server  24 , pervasive application server  26 , and systems management server  28  represent server systems external to PSTN  10  that may be accessed by PSTN  10  over network  20 . 
     In particular, telco application server  22  preferably includes multiple telco specific service applications for providing services to calls transferred to a server external to PSTN  10 . In particular, a call may be transferred from PSTN  10  to telco application server  22  to receive at least one service and then the call is transferred back to PSTN  10 . Such services may also be provided to calls within PSTN  10 , however placing such services at a third party, such as telco application server  22 , is advantageous because adding services and information to PSTN  10  is time consuming and costly when compared with the time and cost of adding the services through telco application server  22 . 
     In accord with an advantage of the present invention, as will be further described, the identity of both the caller and the callee may be authenticated by one of telephony devices  8   a - 8   n , PSTN  10 , or by telco application server  22 . By authenticating the actual identity of the person making a phone call and the person receiving the phone call, rather than the identification of a device from which a call is made and received, an enhanced specialization of services to subscribers may be performed. 
     An authentication service within telco application server  22  may include identification and verification of the identity of a caller and/or callee of a particular call. Such a service may require that subscribers provide voice samples when setting up a subscription. The stored voice samples may then be compared against voice samples received for a particular call in order to authenticate the identity of a current caller or callee of the particular call. 
     Generic application server  24  preferably accesses independent server systems that provide services. For example, a messaging server, a financial server, an Internal Revenue Service (IRS) server, and database management system (DBMS) server may be accessed in HTTP via network  20 . Each of these servers may include a telco service application that requires authentication of the subscriber before access is granted. For example, a financial server may provide a telco service application that allows an authenticated subscriber to access current financial records and request stock quotes from the financial server. 
     Pervasive application server  26  manages services for wirelessly networked devices. In particular, pervasive application server  26  preferably handles distribution of wireless packets of voice and data to wirelessly networked devices utilizing a standard such as short messaging service (SMS) messaging or other 3G standards. 
     Systems management server  28  manages subscriber personalization via the web. In particular, systems management server  28  includes browser technology that includes a provisioning console  30  for establishing a subscriber profile and a management console  32  for managing and updating the subscriber profile. A subscriber preferably accesses the consoles of systems management server  28  via the Internet utilizing a computing system, such as computing systems  34   a – 34   n.    
     The subscriber profile may be accessed at systems management server  28  by other external servers and PSTN  10  via network  20 . In addition, a local copy of a subscriber profile updated in systems management server  28  may be stored within a particular service provider&#39;s data network or telephone network. Each service provider may specify the types of preferences and other information included within a subscriber profile. 
     In particular, a subscriber may provide a voice imprint when establishing a subscriber profile through provisioning console  30 . Other types of authentication information may also be provided including, but not limited to, a password, an eye scan, a smart card ID, and other security devices. In addition, a subscriber may designate billing preferences, shopping preferences, buddy list preferences, and other preferences that enable specialized service to the subscriber when the subscriber&#39;s identity is authenticated from the voice imprint or other identification. 
     Advantageously, a management agent is built into each external server to monitor the services provided by each server according to the authenticated subscriber receiving the services. By monitoring service output according to subscriber, the subscriber may then be billed according to each use of a service. 
     PSTN  10  preferably includes both voice and data signaling networks that interface with network  20  via gateways. Each of the gateways acts as a switch between PSTN  10  and network  20  that may compress a signal, convert the signal into Internet Protocol (other protocol) packets, and route the packets through network  20  to the appropriate server. 
     In particular, the voice network interfaces with network  20  through media gateway  14  which supports multiple protocol gateways including, but not limited to, SIP. SIP is a signaling protocol for Internet conferencing, telephony, presence, events notification and instant messaging. 
     In addition, in particular, the data signaling network interfaces with network  20  through signaling gateway  12  which supports multiple protocol gateways including, but not limited to, parlay protocol gateways and SS7 protocol gateways. Internet servers, such as telco application server  22  may include protocol agents that are enabled to interact with multiple protocols encapsulated in Internet Protocol packets including, but not limited to, SS7 protocol, parlay protocol, and SIP. 
     Identity Authentication And Call Control 
     Looking into PSTN  10 , a telephone network typically includes multiple switches, such as central office switches  11   a – 11   n , that originate, terminate, or tandem calls. Central office switches  11   a – 11   n  utilize voice trunks for transferring voice communications and signaling links for transferring signals between signaling points. 
     Between signaling points, one central office switch sends signaling messages to other central office switches via signaling links to setup, manage, and release voice circuits required to complete a call. In addition, between signaling points, central office switches  11   a – 11   n  query service control points (SCPs)  15  to determine how to route a call. SCPs  15  send a response to the originating central office switch containing the routing number(s) associated with the dialed number. 
     SCPs  15  may be general purpose computers storing databases of call processing information. While in the present embodiment SCPs  15  are depicted locally within PSTN  10 , in alternate embodiments SCPs  15  may be part of an extended network accessible to PSTN  10  via a network. 
     One of the functions performed by SCPs  15  is processing calls to and from various subscribers. For example, an SCP may store a record of the services purchased by a subscriber, such as a privacy service. When a call is made to the subscriber, the SCP provides record of the privacy service to initiate an announcement to a caller to identify themself to the subscriber with the privacy service who is being called. According to an advantage of the invention, authentication of the subscriber receiving the call may be required before the privacy service is initiated for that subscriber. 
     In particular, network traffic between signaling points may be routed via a packet switch called an service transfer point (STP)  13 . STP  13  routes each incoming message to an outgoing signaling link based on routing information. Further, in particular, the signaling network may utilize an SS7 network implementing SS7 protocol. 
     Central office switches  11   a – 11   n  In may also send voice and signaling messages to intelligent peripherals (IP)  17  via voice trunks and signaling channels. IP  17  provides enhanced announcements, enhanced digit collection, and enhanced speech recognition capabilities. 
     According to an advantage of the present invention, the identity of a caller or callee is authenticated according to voice authentication. Voice authentication is preferably performed by first identifying a caller or callee by matching the name or other identifier spoken with a caller name or identifier. Next, voice authentication requires verifying that the voice audio signal matches that of the identified caller or callee. However, in alternate embodiments, the identity of a caller or callee may be authenticated according to passwords, eye scans, encryption, and other security devices. 
     In particular, to perform identity authentication of audio signals received from callers or callees, IP  17  may include storage for specific templates or voice feature information, for use in authenticating callers or callees based on speech. If a specific template is not stored on a local IP  17 , then a remote IP containing the specific template may be accessed via a network. In addition, local IP  17  may access systems management server  28  or another repository for voice imprints to access the specific template. 
     Where IP  17  authenticates the identity of a caller (e.g. the person or subscriber placing a call), a voice identifier (VID) representing the authenticated caller identity is transferred as a signal for identifying the caller. In addition, where IP  17  authenticates the identity of a callee (e.g. the person or subscriber receiving a call), a reverse VID (RVID) including the callee identity is transferred as a signal for identifying the callee. 
     Advantageously, VIDs and RVIDs indicate through text, voice, or video the identity of a caller and a callee. For example, a caller&#39;s name may be transferred as the identity of a caller. Alternatively, a video clip stored with the template may be transferred as the identity of a caller. Additionally, VIDs and RVIDs may indicate the identity of the device utilized by a caller or callee to provide context for a call. Further, VIDs and RVIDs may indicate which system or systems have authenticated the caller or callee identity. 
     After a VID and/or RVID are determined by IP  17 , IP  17  and SCP  15  may communicate to designate which services are available according to VID and RVID. Advantageously, by designating services according to a VID and/or RVID, callers and callees are provided with services and billed for those services independent of the devices utilized by callers and callees. In particular, a  1129  protocol or other protocol may be utilized to enable signal communications between IP  17  and SCPs  15 . In addition, as previously described, voice authentication to determine VIDs and RVIDs may be performed by a third party, such as telco application server  22 . 
     An origin telephony device or destination telephony device may also determine a VID and/or RVID for the caller and/or callee of a call. In particular, telephony devices  8   a – 8   n  and call centers  16   a – 16   n  may function as origin and designation telephony devices. Each of the telephony devices may include a database of voice templates that may be matched to authenticate the identity of a caller or callee. In addition, each of the telephony devices may access a third party, such as telco application server  22 , to authenticate the identity of the caller or callee. In either case, the telephony device transmits a VID and/or RVID with a call to PSTN  10 . 
     Telephony devices  8   a – 8   n  may include, but are not limited to wireline devices, wireless devices, pervasive device equipped with telephony features, a network computer, a facsimile, a modem, and other devices enabled for network communication. Advantageously, as previously described, a voice authentication functioning device may be included in each of telephony devices  8   a – 8   n.    
     However, in addition to authentication according to voice identification and recognition, telephony devices  8   a – 8   n  may be equipped to receive other biometric type input. For example, telephony devices  8   a – 8   n  include an eye print scanner, a fingerprint scanner, and other devices that detect individual human characteristics. Preferably, telephony devices  8   a – 8   n  may receive these other types of biometric input and compare other types of biometric input with previous recorded samples to determine the identity of a caller. 
     In addition, telephony devices  8   a – 8   n  may each incorporate a display that provides a visual output of a VID or RVID. Alternatively, such a display may be provided in a separate device connected to the line in parallel to telephones  8   a – 8   n . According to one advantage of the present invention, the identity of the actual caller or actual callee are output to a display in association with a call. In addition, other context information about the caller including, but not limited to, the device from which the call originates or is answered, ratings for a caller or callee, and other context information may be output to a display in association with a call. 
     Telephony devices  8   a – 8   n  are communicatively connected to PSTN  10  via wireline, wireless, ISDN, and other communication links. Preferably, connections to telephony devices  8   a – 8   n  provide digital transport for two-way voice grade type telephone communications and a channel transporting signaling data messages in both directions between telephony devices  8   a – 8   n  and PSTN  10 . 
     In addition to telephony devices  8   a – 8   n , advanced telephone systems, such as call centers  16   a – 16   n , may be communicatively connected to PSTN  10  via wireline, wireless, ISDN and other communication links. Call centers  16   a – 16   n  may include PBX systems, hold queue systems, private network systems, and other systems that are implemented to handle distribution of calls to multiple representatives or agents. 
     Returning to central office switches  11   a – 11   n , typically, one central office switch exists for each exchange or area served by the NXX digits of an NXX-XXXX (seven digit) telephone number or the three digits following the area code digits (NPA) in a ten-digit telephone number. The service provider owning a central office switch also assigns a telephone number to each line connected to each of central office switches  11   a – 11   n . The assigned telephone number includes the area code (NPA) and exchange code (NXX) for the serving central office and four unique digits (XXXX). 
     Central office switches  11   a – 11   n  utilize office equipment (OE) numbers to identify specific equipment, such as physical links or circuit connections. For example, a subscriber&#39;s line might terminate on a pair of terminals on the main distribution frame of one of central office switches  11   a – 11   n . The switch identifies the terminals, and therefore a particular line, by an OE number assigned to that terminal pair. For a variety of reasons, a service provider may assign different telephone numbers to the one line at the same or different times. For example, a local carrier may change the telephone number because a subscriber sells a house and a new subscriber moves in and receives a new number. However, the OE number for the terminals and thus the line itself remains the same. 
     On a normal call, a central office switch will detect an off-hook condition on a line and provide a dial tone. The switch identifies the line by the OE number. The central office switch retrieves profile information corresponding to the OE number and off-hook line. Then, the central office switch receives the dialed digits from the off-hook line terminal and routes the call. The central office switch may route the call over trunks and possibly through one or more central office switches to the central office switch that serves the called party&#39;s station or line. The switch terminating a call to a destination will also utilize profile information relating to the destination, for example to forward the call if appropriate, to apply distinctive ringing, etc. 
     In the present invention, a VID for the caller may be authenticated at the origin telephony device, the IP, or the destination telephony device and transferred to the central office switch. The central office switch then retrieves and loads profile information according to the caller VID, rather than the OE number for the line. 
     In addition, in the present invention, a reverse VID (RVID) for the callee may be authenticated at the origin telephony device. The caller may then determine whether to open voice communications with the callee, to request an alternate callee, or to hang up. 
     Rvid Authentication Context 
     Referring now to  FIG. 2 , there is illustrated a block diagram of the flow of a voice identifier authenticated by an origin device in accordance with the method, system, and program of the present invention. 
     As depicted, an origin device  40  authenticates a RVID for a current callee. In particular, origin device  40  may include a caller telephony device, as previously described. However, origin device  40  may also include a PBX, call center or other private switching system that manages multiple telephony devices. Moreover, origin device  40  may include network servers, feature servers, and other systems which provide call origination. 
     A service identification/verification (SIV)  41  feature within origin device  40  may determine the identity of a callee and authenticate that identity by comparing a voice utterance made by a callee at destination device  44  with a database of voice samples stored in a voice sample database  43  within origin device  40 . The voice utterance may include, for example, the callee&#39;s name and the callee&#39;s service provider. 
     Where a caller utilizes origin device  40  to initiate a call to a callee at destination device  44 , an intermediary device  42  is accessed to process the call between origin device  40  and destination device  44 . In particular, intermediary device  42  may include, but is not limited to, a PSTN switching network, a PBX, a call center, a private switching system, network servers, telco application servers, Websphere7 (Websphere7 is a registered trademark of International Business Machines, Inc.) servers, and other systems which provide call processing functions. Destination device  44  may include, but is not limited to, a callee telephony device, a PBX, a call center, a private switching system, network servers, feature servers, client side devices, and other systems which provide call receipt. 
     In response to an answer to destination device  44 , origin device  40  preferably transmits a prompt to the destination device, to prompt the callee (the person answering the call) to provide a voice utterance. The voice sample is analyzed by SIV  41  and compared with voice samples in voice sample database  43 , to authenticate the identity of the callee. The identity of the callee is authenticated in a RVID. 
     Origin device  40  may forward the RVID to intermediary device  42  and destination device  44 . Intermediary device  42  may utilize the RVID to specify services provided for the call. The callee may confirm the RVID at destination device  44 . 
     Origin device  40  advantageously includes a display device or other output interface for output of the authenticated RVID to the caller, such that the identity of the callee of an incoming call is provided to the caller. The caller may then decide whether to communicate with the callee depending on the RVID. 
     According to one advantage of the present invention, the caller may also indicate the specify callee for whom the caller is calling. The caller may specify a callee by selecting the callee within the caller&#39;s address book, where the identifier for the preferred callee is then transferred with the call request from origin device  40  to destination device  44 . Alternatively, the caller may enter the name of the preferred callee through voice, text, or keypad input. The preferred callee identity may be displayed at destination device  44  and/or utilized to select a type of ring output by destination device  44 . 
     In the present invention, a RVID preferably authenticates the identity of a callee. However, it is advantageous that the RVID also include other information that provides a context for a call. For example, the GPS location or time zone of the callee location, the device at which the call is receive, and whether a callee has answered on behalf of another, may be included in a RVID. 
     A RVID may be transferred in multiple protocols, including, but not limited to, Interface Definition Language (IDL). A RVID may include a range of information, where each type of information may be tagged or identified in some other manner. For example, the following tagged RVID may be transmitted to represent an authenticated identity of a callee: 
     [callee name] Jon Smith 
     [callee device] Jane Doe&#39;s cell phone 
     [callee location] Central Time zone 
     Origin device  40  may output all the information included in a RVID or a selection of the information. For example, for the tagged RVID described above, origin device  40  may output the following to an input/output interface associated with origin device  40 : 
     A Call picked up by Jon Smith, using Jane Doe&#39;s cell phone@ 
     In addition, origin device  40  may interpret the information included in a RVID. For example, for the tagged RVID described above, origin device  40  may interpret the location and output the following: 
     AIt is currently 4:00 PM at Jon Smith&#39;s location@ 
     Further, origin device  40  may perform other functions with a RVID. For example, origin device  40  may translate the RVID into a particular language. In addition, origin device  40  may request additional information for a RVID from a third party server. 
     With reference now to  FIG. 3 , there is depicted a block diagram of the flow of a voice identifier authenticated by a third party device accessible from an origin device in accordance with the method, system, and program of the present invention. 
     As illustrated, origin device  40  may access a third party device  46  with a request for RVID authentication. Third party device  46  may include a telco application server, accessible via a network, that performs callee authentication. However, third party device  46  may also be a stand alone system or a server connected to a PBX, a private switching system, or a service provider switching system. 
     Third party device  46  may include an SIV  47  feature that receives a voice utterance received via origin device  40  from destination device  44  and authenticates an identity of a callee associated with the voice utterance by comparing the voice utterance with a database  48  of voice samples stored at third party device  46 . Third party device  46  then returns an RVID containing the identity of the callee. Origin device  40  may add additional information to the RVID to provide context for the call, where the additional information is received from intermediary  42  and destination device  44 . 
     Communications between origin device  40  and third party device  46  may be facilitated by intermediary device  42 . In addition, communications between origin device  40  and third party device  46  may be facilitated by a network, such as the Internet, an Intranet, or a private networking service. 
     SIV  47  may implement levels of security in communications with origin device  40 . For example, a secure channel utilizing a secure socket layer may be implemented. In addition, other encryption techniques may be implemented for transfer of information. 
     Alternatively, origin device  40  may access a database of voice samples stored at third party device  46 . Where origin device  40  requests voice samples from third party device  46 , origin device  40  may, for example, request a selection of voice samples for a name identified from a voice utterance. Origin device  40  then authenticates a RVID for the callee. 
     In an example, a voice utterance provided by a callee may include a name and a service provider from which the callee receives service. Origin device  40  may then contact the third party service provider device  46  and request either an authentication of the voice utterance or voice samples for a name identified from the voice utterance. The third party service provider advantageous stores voice samples for each customer, such that identity authentication may be performed. 
     In another example, multiple callers may utilize a single origin device  40 , where each caller has an address book of preferred callees. The database of voice samples for preferred callees of each caller may be stored at origin device  40 , however it would be advantageous to also store that database of voice samples at third party device  46 , such that each of those multiple callers may also utilize alternative origin device, but receive authentication of callees stored within an address book of preferred callees. 
     In general, it is advantageous that a caller may access an address book of preferred callees across multiple diverse origin devices. Therefore, third party device  46  may be accessible across multiple diverse origin devices via network  20 , such that a caller may access an address book at any origin device. 
     Referring now to  FIG. 4 , there is illustrated a flow diagram of a signal flow and processing where an origin device authenticates a callee identity in accordance with the method, system, and program of the present invention. A standard telephone device is assumed for the Atel@ origin device in the present example. However, a similar signal flow may be applied to other types of origin devices. 
     The caller lifts a handset creating an off-hook state in the origin device and a corresponding signal change in state signal to the central office (step S 1 ). In response to detecting an off-hook signal at the central office, call processing commences. Specifically, the central office assigns a register to the call and loads information associated with the OE for the off-hook line into the assigned register. In addition, detecting the off-hook state at the origin device triggers a request to the SCP for a profile of the line subscriber (step S 2 ). The SCP stores profiles for each line subscriber that indicate the services available for the line. The SCP returns the line subscriber profile (step S 3 ) and the central office loads the line subscriber profile into the assigned register for specifying services available during the call (step S 4 ). While the example is described for a line subscriber profile, in alternate embodiments, the VID for a caller may be authenticated by the origin device, the intermediary network, or a destination device and utilized to load a caller profile to specify services for a call. 
     In response to loading a line subscriber profile into the assigned register, a dial tone may be extended from the central office to the origin device (step S 5 ). In return, the caller may input digits that are transmitted to the central office to be utilized to determine the routing of a call (step S 6 ). In particular, a caller may enter digits utilizing, for example, a keypad or voice dialing. In addition, the caller may indicate a name or other identifier for a preferred callee. In particular, the caller may select the preferred callee from an address book stored at the origin device. Alternatively, the caller may speak the name of the callee. 
     The call is then processed through the PSTN and other networks to connect the origin device with a destination device (step S 7 ). A call request is extended to the destination device indicating the subscriber line number and the preferred callee (step S 8 ). Alternatively, the VID of the caller may be indicated if previously authenticated. The name of the preferred callee may be displayed with the subscriber line number and/or may be utilized to select a particular ring for indicating the call request. For example, where multiple people share the destination telephone, a distinct ring may be designated for each person. 
     In response to an answer at the destination device, a pick-up signal is transmitted back to the origin device (step S 9 ). The origin device then initiates the SIV within the origin device (step S 10 ). The SIV initiates a prompting instruction to the callee to provide specific identifying information (step S 11 ). It should be mentioned that although the SIV could passively monitor any speech that the callee may utter, it is advantageous to specifically prompt the callee. For example, the SIV may play an audio prompt message asking the callee to APlease say your full name.@ In addition, the prompt may request other identifying information such as a service provider and subject of the call, for example. Further, the central office may trigger a SIV initiation to an IP at other times during a call. The spoken identification information is then received at the origin device and transferred to the SIV (step S 12 ). 
     Analysis is performed on the spoken identification information to determine a name of a callee and extract speech characteristics information (step S 13 ). A voice template or other voice pattern information may be stored in the origin device according to a callee identity. In addition, voice template information may be stored at a third party server accessible to the origin device. Preferably, the SIV compares the extracted speech information to the stored pattern information, to identify and authenticate the particular callee. If there is a match between the extracted speech information and the stored pattern information, then a RVID signal containing the authenticated identity of the callee is distributable among multiple devices (step S 14 ). Although not depicted, a callee receiving the RVID at the destination device may confirm or deny the correctness of the authenticated identity. If the callee denies the correctness of the authenticated identity, then the authentication process may be performed again, or the callee may be asked for additional identification. 
     If there is not a match between the extracted speech information and the stored pattern information, then a determination as to the number of tries is made (step S 15 ). If more than n tries for authentication have been made, then a denial message is returned to the origin device (step S 22 ). However, if n tries have not yet been made, then another prompting is output to the callee (step S 23 ). 
     In addition to authenticating the identity of the callee receiving a call, the identity of the device utilized to receive the call may be included in a RVID. Each destination device may include an identification number that is returned with the pick-up signal and attached to the RVID of a call at the origin device. Alternatively, where a single OE line includes multiple outlets, the device at each outlet may be identified according to the location of the outlet. 
     In response to an RVID returned to the origin device, the caller is provided with an option of whether to accept the callee. If the caller does not accept the callee, then the call may be terminated (step S 16 ) or an addition request for the preferred callee may be transmitted. If the caller does accept the callee, then the voice channel may be opened at the origin device (step S 17 ). 
     In addition, in response to an RVID returned to the central office, a request is triggered to the SCP for a profile according to the RVID (step S 18 ). In particular, the profile may be stored at the SCP, a telco application server, or other database server accessible from the central office. The callee profile according to RVID is preferably returned to the central office (step S 19 ) and loaded into the assigned register for the call (step S 20 ). The call is then processed according to the services available in the RVID profile (step S 21 ). 
     It should be noted that with each transfer of an RVID, the central office, the SCP, and the origin device may each record and filter the RVID. In particular, filtering the RVID may require blocking all or portions of the content of the RVID. 
     With reference now to  FIG. 5 , there is depicted a flow diagram of a signal flow and processing where a third party system is accessed by an origin device to authenticate a callee identity in accordance with the method, system, and program of the present invention. 
     In response to receiving a pick-up signal at the origin device, a third party connection request is transmitted from the origin device to a network (step S 24 ). In particular, the network may include a service provider server system that is accessible from the origin device by a wireless or wireline connection. In addition, the request for a network connection may first transfer to a central office of a switching system that then forwards the call via a network to a telco application server or other third party server. The network preferably accesses the third party server and creates a communication channel between the origin device and the third party server (step S 25 ). 
     The third party server initiates an identity authentication process for authenticating the identity of the current callee. First, an authorization service application provides a prompting instruction via the origin device to the callee to provide specific identifying information (step S 26 ). For example, the authorization service application may play an audio prompt message asking the callee to APlease say your full name.@ The spoken identification information via a voice channel to the origin device is transferred via the network to the third party server (step S 27 ). 
     Analysis is performed on the spoken identification information to determine a name of a callee and extract speech characteristics information (step S 28 ). A voice template or other voice pattern information may be accessible to the third party server from a local or remote database management system. Preferably, the authorization service application compares the extracted speech information to the stored pattern information, to identify and authenticate the particular callee. If there is a match between the extracted speech information and the stored pattern information, then a RVID signal containing the authenticated identity of the callee is then distributable among multiple devices from the origin device (step S 29 ). 
     If there is not a match of the extracted speech information with the voice templates, then a determination is made as to whether a callee has made more than n tries to speak identification information that has not matched (step S 30 ). If the callee has not made more than n tries, then a prompt is output to the callee via the origin device to provide another spoken utterance (step S 32 ). If the callee has made more than n tries, then a denial message is output to the origin device (step S 31 ). 
     Whether the origin device authenticates a callee identity locally or via a third party system, such as a telco application server, the RVID of a callee is utilized to specify services provided to the callee. An advantage of authenticating a callee identity via a third party system is that the RVID is authorized by a third party system, rather than an origin system that is not as trusted within the network. 
     It should be noted that with each transfer of an RVID, the central office, signaling gateway, telco application server, and origin device may each record and filter the RVID. In particular, filtering the RVID may require blocking all or portions of the content of the RVID. 
     It is important to note that while the present invention has been described in the context of a fully functioning data processing system, those of ordinary skill in the art will appreciate that the processes of the present invention are capable of being distributed in the form of a computer readable medium of instructions and a variety of forms and that the present invention applies equally regardless of the particular type of signal bearing media actually used to carry out the distribution. Examples of computer readable media include recordable-type media, such as a floppy disk, a hard disk drive, a RAM, CD-ROMs, DVD-ROMs, and transmission-type media, such as digital and analog communications links, wired or wireless communications links using transmission forms, such as, for example, radio frequency and light wave transmissions. The computer readable media may take the form of coded formats that are decoded for actual use in a particular data processing system. 
     While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
