MULTIPLE HOST ARRANGEMENT FOR MULTIMEDIA SESSIONS USING SESSION INITIATION PROTOCOL (SIP) COMMUNICATION

摘要

A system for conducting multimedia SIP sessions via multiple hosts, such as a PC (32) and a telephone (34). Display data is transmitted to the session participant via the PC (32), and voice data is transmitted to the session participant via the telephone (34). An SIP split user agent proxy server receives an incoming SIP call from a calling client and transmits call signals associated with display data to the PC (32) for allowing the PC (32) to display documents, video, graphics, and/or text related to the call. Call signals associated with voice are transmitted to an SIP emulation client coupled to the telephone (34) for allowing the telephone (34) to engage in the voice communication.
