  • Method and apparatus for integrated multimedia call control
    Patent number: 6826272
    Abstract: Method and apparatus for integrated multimedia call control. A unified way to manage incoming calls is provided for users who have both a public switched telephone network (PSTN) telephone and a computer workstation with a multimedia data communications client such as a client specified in International Telecommunication Union (ITU) Standard H.323. Calls from a PSTN phone in the network can be routed either to the user's PSTN telephone or the audio handling portion of the user's multimedia data communications client software. The audio portion of calls from a multimedia data communication client in the network can be routed either to the user's PSTN telephone or to the audio portion of the user's multimedia data communication client. Users can thus control PSTN and multimedia internet telephony calls in a consistent manner.
