## Background
CLAIM OF PRIORITY
This application claims the benefit of U.S. Provisional Application 60/746,367, “SoftPhone With Simplified Calling,” filed on May 4, 2006, by Lon-Chan Chu, Pitak Leelaphisut and Praveen Kumar Vemparala, incorporated herein by reference in its entirety.


BACKGROUND
Voice over Internet Protocol (VOIP) is a technology that allows users to make telephone calls using a broadband Internet connection instead of a traditional telephone line. Some services using VOIP may only allow users to call other people who are also using VOIP. However, many services also allow users to call anyone who has a telephone number—including local, long distance, mobile, and international numbers. While some services only work over a computer or a special VOIP phone, other services allow use of a traditional telephone through an adaptor.
To encourage the use of VOIP, technology providers have sought ways to make VOIP more convenient and efficient to use. One attempt to encourage the use of VOIP includes the use of hyperlinks. Developers of VOIP applications have implemented technology that allows providers of content to include hyperlinks in the content. Users can initiate telephone calls by executing (e.g., selecting) the hyperlink. However, the use of these hyperlinks has been limited. For example, some hyperlinks only provide the user with the ability to initiate a telephone call to a preset telephone number.
Even with the hyperlinks, the user typically will still need to perform manual steps for many administrative functions. Additionally, some telephone numbers may only be valid during certain time periods. Outside the time periods, the hyperlink will not be useful because the target telephone number is not valid.
SUMMARY
The technology described herein facilitates the use of a communication application with the introduction of a new hyperlink.
A hyperlink is added to user interface code to provide a user with an easy way to access various functions of a communication application. The hyperlink can provide target telephone numbers in different formats, specify a web page (or other content) to be displayed during a call, specify rules to be used to identify a telephone number from a set of telephone numbers, and include commands to manage the communication application.
One embodiment includes receiving a selection of a link in a first interface, establishing a voice connection based on the link, accessing content over a network based on the link, and presenting the content while the voice connection is operational. Another embodiment includes receiving information from a link selected in a first interface, accessing a command in the information, and executing the command using a voice communication application. Another embodiment includes receiving a selection of a link in a first interface, accessing a rule referenced in the link, choosing a communication target based on evaluating the rule, and establishing communication with the target using a communication interface.
The technology described herein can be implemented using hardware, software, or a combination of both hardware and software. The software used is stored on one or more processor readable storage devices including hard disk drives, CD-ROMs, DVDs, optical disks, floppy disks, tape drives, RAM, ROM, flash memory, or other suitable storage devices.

DETAILED DESCRIPTION
The technology described herein facilitates the use of a communication application with a hyperlink. One or more of the hyperlinks are added to user interface code to provide a user with an easy way to access various functions of a communication application. The hyperlink can provide target telephone numbers in different formats, specify a web page to be displayed during a call, specify rules to be used to identify a telephone number from a set of telephone numbers, and include commands to manage the communication application. For example, an advertisement in a web page may include a hyperlink to initiate a telephone call to a store and to cause the user's browser to simultaneously navigate to the web page for that store.
FIG. 1 is a block diagram depicting one embodiment of a system that provides for communication over a network using the hyperlink described herein. In one example implementation, the communication is established using VOIP technology. FIG. 1 depicts client computing device 10 in communication with Internet 12. Client computing device 10 can be any suitable computing device including a personal computer, notebook computer, handheld device, mobile telephone, etc. Client computing device 10 includes software and/or hardware to allow communication over Internet 12. For example, client computing device may include a VOIP software application that communicates over a network interface.

When a web page is loaded, a browser calls a browser plug-in to perform a function. When a user hovers on a text string, Browser 30 calls browser plug-in 32 to process the text string. URL Moniker 34 receives URLs that are in code implementing a user interface within Browser 30 and looks up the appropriate protocol handler for these URLs. LiveCall Handler 36 is one example of a protocol handler. As discussed above, one aspect of the technology described herein is a new hyperlink. This hyperlink is referred to as a LiveCall hyperlink. LiveCall Handler 36 is the protocol handler for the LiveCall hyperlink.
SoftPhone 40 includes Authentication Manager 42, which is a software module that authenticates users prior to using SoftPhone 40. In some embodiments, Authentication Manager 42 also verifies that a user is authorized to perform the actions requested by the user. FIG. 2 shows Authentication Manager 42 in communication with plug-in 32 and LiveCall Handler 36.
After a user is authenticated, Authentication Manager 42 will pass control to parser 44 or another module. Parser 44 is a software module that parses a URL into various components. Parser 44 will communicate these components to Signal and Voice Engine 46, Business Intelligence 48, Presentation Logic 50 and Hyperlink Redirector 52.
Signal and Voice Engine 46, which is also in communication with Authentication Manager 42, provides the engine for initiating and maintaining a VOIP telephone call. Signal and Voice Engine 46 is in communication with Address Book 58. In one embodiment, Address Book 58 stores contact information for various people associated with the user. Address Book 58 can be part of a personal information management application or a data store that is dedicated to SoftPhone 40.
Business Intelligence 48 is a data store which stores information about the use of SoftPhone 40 for Business Intelligence applications. Presentation Logic 50 provides a user interface for SoftPhone 40. Hyperlink Redirector 52 can be used to redirect either Presentation Logic 50 or Browser 30 based on a command or information in a URL. In one embodiment, Hyperlink Redirector 52 is in communication with Browser 30.
FIG. 2 contemplates the environment where the hyperlink is used in code for a web page displayed in Browser 30 and the user is using SoftPhone 40 to make a VOIP call via Internet 12 or other network. In another embodiment depicted in FIG. 3, the hyperlink can be used within an application other than a browser. For example, a hyperlink can be used in a word processing document, spreadsheet, or any other application. FIG. 3 shows client computing device 10A including SoftPhone 40, Browser 30, Windows Shell 60, and Application 64. SoftPhone 40 and Browser 30 include the components depicted in FIG. 2. Windows Shell 60 is an interface for the operating system.

The source parameter “Src” in a LiveCall hyperlink indicates the source context where this LiveCall hyperlink is clicked or executed. This information is useful for business intelligence. The source parameter can be combined with other parameters. Parameters in a LiveCall hyperlink are concatenated by the ‘&’ sign. Consider the following examples:

    (1) LiveCall:Phone=7069606&Src=Messenger/Contact/Home; Place a PC-to-Phone call using the home phone number listed in the contacts of Messenger (Instant Messaging).
    (2) LiveCall:Online=JohnDoe@hotmail.com&Src=Messenger/Buddy; Place a PC-to-PC call using the online presence ID listed in the buddy list of Messenger.
    (3) LiveCall:?Signup&Src=Hotmail/Ads; Go to the signup web site to start signup process, where this hyperlink is listed in the ads section of Hotmail (web based email service).


One feature of the LiveCall hyperlink is to make a telephone call and browse a designated web site at the same time. This may be important, for example, for commercial calls to allow the customer to view the order information online. Consider the following examples:

    (1) LiveCall:Phone=7069606&Src=YellowPage/Pizza&URL=http://www.bestpizza.com; Place a PC-to-Phone call using the pizza store phone number listed in the yellow pages (e.g., a web site implementing a yellow pages directory). At the same time, the user can browse to the web site at http://www.bestpizza.com.
    (2) LiveCall:+886229212154&URL=http://www.flowerdelivery.com.tw; Place a PC-to-Phone call using an international phone number to order a flower delivery in Taiwan. At the same time, the user can browse to the flower delivery web site at http://www.flowerdelivery.com.tw to view the selection and price.


The LiveCall hyperlink allows for calling rules that select a telephone number based on the calling rule. The syntax of the rule is either a sequential list of telephone numbers or a condition with two lists of phone numbers:












Rule={ <sequential list of phone numbers separated by a comma> }


Rule={ <condition, either true or false> }?{ < list of phone numbers in


true condition> }:{ < list of phone numbers in false condition> }









Consider the following examples:

    (1) LiveCall:Contact=JohnDoe@hotmail.com&Rule={home,work,mobile,pc}; Place a PC-to-Phone call using the phone numbers listed in the contact information (or address book) associated with the contact having an email address of JohnDoe@hotmail.com, but the order of the numbers to call is home number first, work number second, mobile number the third, and finally making a PC-to-PC call as the last resort. That is, if the target is not reached using the home number, try the work number; and if the target is not reached using the work number then try the mobile number; and if the target is not reached using the mobile number then try the PC.
    (2) LiveCall:Contact=JohnDoe@hotmail.com&Rule={time>8:00 am&time<5:00 pm}? {work,mobile}: {home,mobile}; Place a PC-to-Phone call using the phone numbers listed in the contact information (or address book) associated with the contact having an email address of JohnDoe@hotmail.com, but the order of the numbers to call depends on the time of the day. At work hours (from 8 am to 5 pm), the order is work number first and then mobile number. At other times, the order is home number first and then mobile number.


FIG. 5 is a high level flowchart describing one embodiment of a process for using the LiveCall hyperlinks. In step 200, code for a web page or other interface is created. In step 202, one or more LiveCall hyperlinks are added to the code. In step 204, the code is distributed. In one embodiment, the code can be distributed via Internet 12 when users navigate to an appropriate web site. In other embodiments, the code is part of an application that is distributed through the Internet, retail stores or other means. In step 206, a user accesses the code. For example, a user may navigate to a web site or launch an application. In step 208, the user selects a LiveCall hyperlink. For example, a web site may include an advertisement for a certain good, where the advertisement indicates that if the user clicks on the hyperlink the user will call the store who sells that good. Other examples are also relevant. In response to selecting the LiveCall hyperlink, the hyperlink is executed in step 210.
FIG. 6 is a flowchart describing one embodiment of a process performed in response to a user clicking on or otherwise selecting a LiveCall hyperlink in a web page, document, file or user interface (see step 210 of FIG. 5). A hyperlink is typically expresses as a Uniform Resource Locator (URL). In step 300, the URL of the selected LiveCall hyperlink is passed to URL Moniker 34. In step 302, URL Moniker 34 looks up the appropriate protocol handler based on the header information in the URL (e.g., “LiveCall:”). In step 304, the URL Moniker 34 passes the URL to the appropriate protocol handler. In the case of the LiveCall hyperlink, the URL is passed to LiveCall Handler 36. In step 306, LiveCall handler 36 confirms with the user that the user wants to execute the URL. In some embodiments, step 306 is optional and can be skipped. In step 308, LiveCall Handler 36 launches SoftPhone 40. In some embodiments, if SoftPhone 40 is already running, then it does not need to be launched again. SoftPhone 40 includes a graphical user interface that comprises a keypad for dialing, a telephone number display area, an area that displays call history, an area that displays service provider information, an area that displays telephone call information, and (optionally) an area to display web or network content.
In step 310, LiveCall Handler 36 will pass the URL to SoftPhone 40. In one embodiment, the URL is initially passed to Authentication Manager 42. If the user is not authenticated (step 312), then Authentication Manager 42 will authenticate the user. In one embodiment, this will include providing a log-in screen where the user can provide a username and password. If the user does not properly authenticate, the process of FIG. 6 will terminate. After authenticating the user, Authentication Manager 42 will verify whether the user is authorized to perform the function identified in the hyperlink in step 316. Note that if the user was previously authenticated (see step 312), then step 314 will be skipped and the process will proceed to step 316 to determine whether the user is authorized.
In step 318, the URL representing the hyperlink (e.g., “LiveCall:Contact=JohnDoe@hotmail.com&Rule={time>8:00 am&time<5.00 pm}? {work,mobile}:{home,mobile};”) will be passed to parser 44 which will check the syntax of the URL and decompose the URL into various components. In step 320, parser 44 will send the appropriate components to Signaling and Voice Engine 46, Business Presentation Logic 50 and Hyperlink Redirector 52. In one embodiment, the command, callee and calling rule will be passed to Signal and Voice Engine 46, the command will be passed to Presentation Logic 50, and the command and hyperlink will be passed to Hyperlink Redirector 52. In step 322, parser 44 will save the data (e.g. all of the components) to Business Intelligence data store 48. In step 324, Signaling and Voice Engine 46 will resolve any rules and resolve any parameters using the Address Book 58. For example, if a target is identified by a contact or computer name, Address Book 58 will be used to translate that contact to a telephone number or translate the computer name to a IP address. As an additional example, if a rule tests whether the time of a call is within a predetermined range then Signaling and Voice Engine 46 will test whether the current system time is within that predetermined range and select the appropriate telephone number (see example above).
In step 326, Signaling and Voice Engine 46 will establish a voice connection (if the hyperlink includes a command for a voice connection to be established) based on the URL. In step 328, Presentation Logic 50 will display a corresponding interface for the command in the hyperlink. In step 330, the Hyperlink Redirector 52 will redirect according to the hyperlink. If the command in the hyperlink is to access or otherwise manage an account, then in step 332 Hyperlink Redirector 52 redirects the user to a particular management page within the user interface for SoftPhone 40 or Browser 30, and the command is executed. This redirection may include a cross domain authentication. That is, if the user is already authenticated via SoftPhone 40, then the user will not need to authenticate a second time. In one example, a cross domain authentication credential is created and that credential will be provided to the management application or management page so that the user will be authenticated and will not need to type in another password. In step 330, if the command in the hyperlink is to make a telephone call, Hyperlink Redirector 52 will redirect the hyperlink without any cross domain authentication credential (step 334).
The hyperlink can include a telephone number and a web site address. Hyperlink Redirector 52 will cause Browser 30 to show the target web site associated with the address included in the hyperlink. This web site will be provided to the user during the telephone call (e.g., step 334) via the browser or the user interface for the SoftPhone. In some embodiments, the web site will be loaded concurrently with the establishment of the telephone call or shortly thereafter.
FIG. 7 is a flowchart describing one embodiment of a process performed in response to a LiveCall hyperlink being selected when operating within the embodiment of FIG. 3. That is, a hyperlink is in an application. In step 350, application 64 issues a command to an API. For example, a ShellExecute( ) or ShellExecuteEX( ) is issued to Window Shell 60. In step 352, Windows Shell 60 will look up the appropriate protocol handler. If the protocol handler is found (step 354), then Windows Shell 60 will launch the Protocol Handler in step 360. For example, LiveCall Handler 36 can be launched. The Protocol Handler can exist separate from Browser 30 or as part of Browser 30.
Prior to operation, a LiveCall protocol handler needs to be registered. Two implementations are possible for registering a protocol handler. One is to register the protocol handler with Windows Shell. The other is to register the protocol handler with the browser. One advantage of registering the protocol handler with the browser is that the protocol handler can perform a sanity check to insure that the user has a chance to confirm the execution of the URL before the application is actually launched. This may be important to protect a user from drive-by executions of the URL while the user is visiting a web site.
In step 362, the URL is passed to the protocol handler. In step 364, the protocol handler launches SoftPhone 40, if not already launched. In step 366, the protocol handler passes the URL to SoftPhone 40. After step 366 the process will continue at step 312 of FIG. 6.
If the Windows Shell 68 did not find an appropriate protocol handler (step 354), then Windows Shell 60 will ask Browser 30 to locate the appropriate protocol handler in step 370. If Browser 30 is able to find the appropriate protocol handler, then it will pass the URL to URL Moniker 34 in step 374. In step 376, that process will continue in step 302 of FIG. 6. If no appropriate protocol handler was found in step 372, an error is returned to step 380.
FIG. 8 is a block diagram depicting one example of implementing a PC-to-Phone call by a LiveCall hyperlink (e.g., LiveCall:+14257069606). FIG. 8 depicts Client computing device 10 in communication (via Internet 12) with a call signaling server 381 of interface 16, which itself is in communication with a call signaling server 383 of a Telco provider 382 via Internet 12. Signaling server 383 is in communication with Public Switched Telephone Network (“PSTN”) gateway 384 of Telco provider 382. PSTN gateway 384 is in communication with client computing device 10 via Internet 12 and with telephone 386 via PSTN 385.
SoftPhone 40 in client computing device 10 sends a call signaling message (including the phone number specified in the LiveCall hyperlink) to the call signaling server 381 (see 390a). Call signaling server 381 authenticates the user and routes the call signaling message to the appropriate telco provider 382 (see 390b). When the call signaling server 383 at the telco provider 382 receives the call signaling message, it authorizes the call and terminates the call to the appropriate PSTN Gateway 384 (see 390c). The PSTN Gateway routes the call to the destination telephone line (see 390d). When a user picks up the telephone 386 at the destination telephone line, the voice stream will be established among SoftPhone 40 (in client device 10), PSTN gateway 384, and PSTN telephone 386 (see 390e and 390f). During the telephone call, SoftPhone 40 can access and display web content or cause the browser to access and display web content.
Telephone 386 can be PSTN telephone or mobile/cellular phone. In the case of a mobile/cellular phone, PSTN gateway, PSTN network, and PSTN telephone can be replaced with mobile gateway, mobile network, and mobile phone, respectively. In another embodiment, the PSTN telephone can be replaced with mobile gateway, mobile network, and mobile phone. In one implementation, SIP (Session Initiation Protocol) is used for call signaling.
FIG. 9 is a block diagram depicting one example of implementing a command to access the call history (e.g., using a LiveCall hyperlink “LiveCall:?CallHistory”). FIG. 9 depicts Client computing device 10 in communication (via Internet 12) with a cross domain authentication server 392 of interface 16, which itself is in communication with a call history server 394 of Telco provider 382 via Internet 12. Call history server 394 is in communication with client 10 via Internet 12.
SoftPhone 40, on client 10, launches the browser to process the internal call history URL. The browser on client 10 sends the internal call history URL to the cross-domain authentication server 392 (see 396a). Cross-domain authentication server 392 authenticates the call history URL and forwards the call history URL to the appropriate telco provider (see 396b). When the call history web server 394 at the telco data center 382 receives the call history URL, it starts the call history query process and displays the call history landing page. From now on, the browser on client 10 can directly communicate with the call history web server 394 for call records. (see 396c).
