Document Type and Number:
WIPO Patent Application WO2007021446
Kind Code:
A8
Abstract:
Providing non-voice capabilities relating to a phone call at a computing device includes receiving a request to begin a telephone call from a first telephone to a second telephone, wherein the requesting is performed using messaging between computing devices connected via a computer network, and wherein the messaging is part of a signaling phase dialog. The signaling phase dialog may be used in providing information associated with the identity of parties of the telephone call. Commencing a call phase dialog between the computing devices may be performed after the telephone call is established over the public switched telephone network. The call phase dialog may allow messages relating to the telephone call to be passed between the computing devices, at least while the telephone call is in progress. The dialogs and messaging may be performed using session initiation protocol (SIP) or another computer communication protocol.
