     This application is a continuation-in-part of U.S. Ser. No. 12/496,165, filed on Jul. 1, 2009 (and entitled Internet Protocol Text Relay For Hearing Impaired Users), which is incorporated in its entirety herein by reference. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention generally relates to the field of telecommunications. In particular, the invention relates to a system and method for assisting the hearing impaired by a communications assistant while also facilitating the calling party&#39;s Caller ID into XML text or to be shown on any telephone for hard of hearing party to see. 
     2. Description of the Related Art 
     There is a necessity for humans to communicate with one another. There have been many inventions to assist such communication, especially in the field of devices or services for the deaf. However, most of these devices have been created using BAUDOT protocol, used for modem to modem communication, which was communicating at 45.5 baud. Commonly known devices are TDD or Teletype TTY. Some of the modem devices are TDD consisting of keyboard and display with built in modem. 
     Due to the proliferation of the internet, the present invention will provide a mechanism for to people to communicate with each other regardless of geographic boundaries. The present invention may be used with any telephone currently available or anything that will be invented in the future to assist the communications assistant or the operator. The present invention may replace many of those devices as it uses internet protocol which works over a global communications network. The present invention will further assist companies and service providers who are in the business of translating and transcribing. 
     The advantage of this invention described herein will allow the end user device to receive text or captioned text to be displayed. The words spoken by the called party will be transcribed by an operator or communications assistant for streaming as text to the device of an end user who is hearing impaired. The device may be any of IP phone, Blackberry, WM-Windows Mobile, Symbian (an operating system of NOKIA), Java, Flash, XML, etc., as is well known to those skilled in the art. 
     Accordingly, there is now provided with this invention an improved communications system for the hearing impaired effectively overcoming the aforementioned difficulties and longstanding problems inherent in the voice communication field. Additionally, this invention further promotes functional equivalency for the hard of hearing by providing Caller ID of the calling party instead of the Caller ID of the relay service provider. Other service providers currently providing IP CTS or IP Relay lack caller ID functionalities for the hard of hearing. 
     SUMMARY OF THE INVENTION 
     According to one aspect of the invention, a system for communication is disclosed comprising a first telephone for transmitting and receiving voice and text by IP communication, a transceiving device for transmitting and receiving voice and text communication connected by ip to the first telephone, and a second telephone operatively connected to said transceiving device for transmitting voice communication thereto. The transceiving device provides the calling party&#39;s caller identification. 
     Another aspect of the invention includes a method of communication comprising sending a first voice communication from a first telephone to a second telephone through a transceiving device and receiving a text message from the transceiving device. The text message is a text of a voice communication from the second telephone in response to the first voice communication. 
     Still another aspect of the invention includes a method of communication comprising receiving on a transceiving device a first voice communication from a first telephone connected by ip to a second telephone and providing text transcription of the voice communication from the second telephone to the first telephone by the transceiving device. 
     Still another aspect of the invention includes a method of communication which displays the caller ID of the calling party to the hard of hearing party, and vice versa, and not the caller ID of the service provider. Through the use of other service providers and their current technology, the hard of hearing user has no idea who&#39;s calling him or her until the calling party reveals him or herself in voice and/or via captioning to the hard of hearing user. 
     As will be appreciated by those persons skilled in the art, a major advantage provided by the present invention is that hard of hearing persons may communicate by means of a telephone to persons who can hear, as well as benefit from a Caller ID pass through feature which is unavailable through other current service providers in the market today. Additional objects of the present invention will become apparent from the following description. 
     The method and apparatus of the present invention will be better understood by reference to the following detailed discussion of specific embodiments and the attached figures which illustrate and exemplify such embodiments.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The following preferred embodiment as exemplified by the drawings is illustrative of the invention and is not intended to limit the invention as encompassed by the claims of this application. 
     A system and method for providing communication for a hearing impaired person is disclosed herein using the following definitions and abbreviations: 
     ACD: Automatic Call Distribution, software or hardware based systems with ACD software generally used in call centers. 
     SQL: Structured Query Language, used for Database 
     ANI: Automatic Number Identification or Caller ID 
     DNIS: Dialed Number Identification Service. This allows a service provider or call center agent to know which number the caller dialed or wishes to dial. 
     CRM: Customer Relationship Manager. This is typically used by call centers and their agents to manage the call or treat the call in a window. 
     Stored Procedure: a function in SQL which updates/writes to the SQL Database. This functions as a small program. 
     IP Phone: Any Internal Protocol based phone, for example, a Cisco 7960 which is capable of receiving XML feed. 
     URL: Uniform Resource Locator. This is commonly known as a web address. 
     XML: Extended Mark-up Language, as is commonly used in websites. 
     Service URL: a pre-determined route which allows an IP phone to fetch its XML/Data feed. 
     DB: Database 
     Caller ID: Automatic display of caller&#39;s telephone number on recipient&#39;s phone. 
     Relay center: An intermediate between the connection of a caller&#39;s telephone and a recipient&#39;s telephone for the use of a person hard of hearing. Such a relay center is commonly referred to in the industry as “Services for the Deaf”, “Captioning Service”, “IP Relay Center”, “Relay Center for the Deaf”, a transceiving device, or the like. 
     The system, as illustrated generally in  FIG. 1  shows a telecommunications system between a phone  1  and a phone  2 . The user of the phone  1 , as contemplated here, would be typically a hearing impaired person or one commonly referred to as hard of hearing. The user of phone  2  would typically be a person who can hear. 
     In order for a hearing impaired person to use the telecommunications system of the present invention, which would enable phone  1  to receive the text transcription of the voice communication of phone  2 , the user of phone  1  must be a registered user. To register for the service, the hearing impaired customer must first visit a hosting website, such as PhoneCaption.com. To register for use, the hearing impaired person would typically enter personal profile data, for example, first and last name, address, primary phone number (the one on which he wants to receive text), and his e-mail address. 
     Upon entering the above information, the user is authenticated or registered and typically provided with an 800- or 888- or 10-digit number provided by the relay service, which is matched with their primary registered number where they will be receiving the phone calls. The user of phone  1  would give out this 800- or 888- or any other ten-digit number assigned by the relay service provider to their friends, family, or business associates where they will be receiving calls. Upon registration and authentication of such a user, the user is in the database of the service provider so that he or she can make or receive phone calls with transcriptions. 
     When the phone  1  user wishes to make a call, he/she calls the pre-assigned 800-number for their account and when prompted, he/she enters the number they wish to call, or Phone  1  user can dial a direct 10-digit number of Phone  2 . Phone  2 , however, does not have to be a registered user as he/she can hear/speak and has no need for transcription or captioning. When phone  2  receives a phone call, that phone call must be originated from phone  1  via the 800- or ten-digit number assigned by the relay service provider or direct dial 10-digit number, to use captioning service, it shall show Caller ID of Phone  1  through the following process. When the call is received at the call/relay center, the system shall see the incoming Caller ID of Phone  1 . When the second leg of the call is made from the CA to Phone  2 , the system shall appear to the phone company as “Caller ID” of Phone  1  so that the Caller ID of Phone  1  is released to Phone  2 . The system will recognize Phone  1  user&#39;s Caller ID and shall store the same in a temporary database to be forwarded to Phone  2  when the call is delivered. Phone  1 &#39;s Caller ID passing through the local phone network or IP network delivered to the call center. At the call center, the database server which maintains the intelligence of all call traffic/call treatment/CRM/ACD shall accept the Caller ID and send the same on the outgoing call thus enabling the Caller ID of Phone  1  to be displayed on Phone  2 . 
     Phone  1  may be an IP phone or any phone capable of displaying text from an internet connection, for example, IP Phone, BlackBerry, WM-Windows Mobile, Symbian (an operating system of NOKIA), Java, Flash, XML, etc. Phone  1  may be any telephone from any carrier with the ability to fetch XML text by having the service URL programmed into the phone. Phone  1 , having auto refresh, would get the newest text in XML format automatically. 
     The phone  1  is operatively connected to an ACD (automatic call distribution) relay center  4  by connections  6  and  7 . Such connections  6  and  7  may be any type of connection regardless of connection media, for example, internet, wireless, 3G, GSM, TDMA, CDMA, or any packetized network. The user&#39;s phone  1  may further include any connected devices necessary to perform multi linked duplex communication and any internet connected device(s) capable of displaying internet content to perform communication. 
     An agent or a communications assistant  8  would typically use a headset connected to a computer  10 . Of course, as is well known in the art, the agent may be wholly or partly replaced by voice recognition software capable of providing a text transcription of voice communication. The computer  10 , running CRM and speech recognition software would be operatively connected to the ACD relay center  4  by any connection capable accepting calls from the ACD environment regardless of connection media, for example, wireless, 3g, gsm, tdma, cdma or any packetized network. The ACD relay center would be further connected by connection  12  to a party with whom the user wishes to communicate using phone  2 . Connection  12  may be any internet connection regardless of connection media, for example, wireless, 3g, gsm, tdma, cdma or any packetized network. The ACD relay center, has the wherewithal to accept the Caller ID, route the call and conference the call with an operator or communications assistant/agent. In the process of setting up this conference call between three parties, the program has the intelligence to move the Caller ID data from the incoming line of Phone  1  through the outgoing line to Phone  2  while maintaining the relay operator or communications assistant in an inert position without its own Caller ID identification during the conference call. 
     The ACD relay center is connected to the internet  14  by connection  16  to a database server  18 . Connection  16  is a multi linked, multi tier ip capable of handling multiple calls. The operator  8  together with the computer  10  and database server  18  includes any devices necessary to perform multi-linked duplex communication. Updated text, including Caller ID of the originating phone, from the relay center is sent to the database  18  which has wherewithal to hold the Caller ID and to re-insert Caller ID into the outgoing call during a conference call set up with Phone  2  which will be delivered to either internet or via traditional telephone company. 
     The database is connected to the internet  14  via a web server  24  and connections  26  and  28 . This server is typically a Service URL Server. Phone  1  may be connected to the internet by connection  30  whereby the service URL responds to phone  1  with updated text. 
     In use, the system of the present invention operates as a captioned telephone relay service and a method by which a stream of text may be provided a hearing impaired person. For example, a hearing impaired person, using phone  1  may wish to call a person of hearing on phone  2 . Although phone  1  dials the number of phone  2 , the outbound call is directed to the ACD relay center. To the hearing impaired person, it may appear as a regular connection. However, the reply to all of the voice communication from the hearing impaired person is a text transcription of the voice communication from the callee as transcribed by an agent or software at the ACD location. Phone  1 &#39;s Caller ID is being delivered to Phone  2  as though he called Phone  2  directly instead of sending Caller ID of ACD center. This enables the hard of hearing user to maintain his own identity as though he made the call. This type of identity is essential as we see in the normal course of business, a person may call a credit card company or any other company which relies on the caller&#39;s Caller ID to identify the caller. Furthermore, this functionality provides functional equivalency to the hard of hearing user so that he or she may not be identified as a hard of hearing person who needs relay assistance to the called party, thus eliminating any discrimination. Most deaf and hard of hearing individuals do not like their callers to know they are using a relay center. 
     In reverse, a person of hearing from phone  2  may call the ACD relay center to request the operator connection with a hearing impaired user of phone  1 . Once the call has been established among the parties, Caller ID of Phone  2  is being delivered to Phone  1  and the operator will continuously transcribe the conversation for transmission of text to the end user until the completion of the call. 
     When a person of hearing from phone  2  calls a hard of hearing person at phone  1 , the call first arrives at the ACD. The ACD connects to the database SQL and determines the type of call to route the call to the agent along with call information. Such call information would be, for example, ANI/DNIS, Caller ID with the CRM Integration for that call. The agent then accepts the call with the information and makes a call to the person hard of hearing at phone  1  based on the information provided from the CRM, for example, the phone number.  FIG. 2  illustrates the screen of the agent receiving such information. Phone  1  then answers the call. When Phone  1  receives the call, the Caller ID shown on his telephone will be that of Phone  2 . The agent conferences phone  1  and phone  2  together so that both parties can hear each other. The agent listens into the conference (three party call) and transcribes the voice of phone  2  into text delivered to SQL. The stored procedure updates the new text automatically to the database on the SQL Server. Typically, the agent will use both his own typing skills together with the assistance of speech recognition software to transcribe the text. Of course, as is known to those skilled in the art, this transcription may be performed either entirely or in part by software. 
     This process is possible through the agent&#39;s CRM integration with the data base (SQL residing on the SQL server). Phone  1  is preregistered with a relay/caption service provider and serviced by any carrier, and programmed with a Service URL directed to Service URL Server. 
     At phone  1 &#39;s request, the Service URL transmits the latest transcribed text in XML format. The Service URL Server fetches the data from the DB every time phone  1  makes a request. Text from the Service URL is seen on the screen of phone  1 . As the URL auto refreshes, the XML is updated with the latest data/text. The new text is seen on the screen of phone  1 . 
     Thus, the present invention discloses a process by which a device or service can facilitate communication between persons of hearing and those hard of hearing using any IP telecommunication device. The hard of hearing user will be able to receive text over any IP display device which is being transcribed by an operator or software from an interne connected computer. In this way, a hard of hearing person will be able to see the Caller ID of incoming call of the hearing party and hear the voice of the party over the phone alongside seeing the same transcribed into text over the display of an IP device. The procedure automatically updates the text to hard of hearing users. The text is delivered to the hard of hearing user by means of XML. 
     In the business of Captioned Phone Service, as of today no one else in the industry has created the technology to send Caller ID from calling party to called party or vice versa. Instead the Caller ID of the call center or relay center or captioning center is delivered. This type of service is not functionally equivalent to the hard of hearing community. 
     Although the particular embodiments shown and described above will prove to be useful in many applications in the hearing impaired communication field and the general art of text communication and sending and receiving caller ID, to which the present invention pertains, further modifications of the present invention will occur to persons skilled in the art. All such modifications are deemed to be within the scope and spirit of the present invention as defined by the appended claims.
