Multiple host arrangement for multimedia sessions using session initiation protocol (SIP) communication
First Claim
1. A multihost system for communicating information to a participant in a session initiation protocol (SIP) multimedia session, comprising:
- a first host having an SIP signaling stack and a first interface for communicating to the participant information of a first media type transmitted in the SIP session; and
a second host coupled to the first host and having a second interface for communicating to the participant information of a second media type transmitted in the SIP session.

Abstract
A system for conducting multimedia SIP sessions via multiple hosts, such as a PC and a telephone. Display data is transmitted to the session participant via the PC, and voice data is transmitted to the session participant via the telephone. 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 for allowing the PC 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 for allowing the telephone to engage in the voice communication.

10. A multihost system for communicating information to a participant in a session initiation protocol (SIP) multimedia session, the system comprising:
-
a first endpoint including a first SIP signaling stack;
a second endpoint including a second SIP signaling stack; and
a server coupled to the first endpoint and the second endpoint, characterized in that the server receives an incoming SIP call from a calling client and transmits call signals associated with a first media type to the first endpoint for allowing the first endpoint to receive information of a first media type during the SIP session and transmits call signals associated with a second media type to the second endpoint for allowing the second endpoint to receive information of a second media type during the SIP session. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

30. In a multihost system, a method for communicating information to a participant in a session initiation protocol (SIP) multimedia session, the method comprising the steps of:
-
receiving an incoming SIP call from a calling client, the incoming SIP call including information of a first media type and information of a second media type;
communicating to the participant the information of the first media type via a first host; and
communicating to the participant the information of the second media type via a second host coupled to the first host. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
