The present invention monitors call signaling events stemming from a circuit-switched call between a caller and a called party and controls a packet-session between user agents on respective endpoints associated with the caller and called party. The endpoints may include any type of computational device capable of facilitating the packet-session over a packet-switched network. Control of the user agents may be provided via a proxy for the user agents and may use the session initiation protocol (SIP), or like session control protocol for communications.

Integrating multimedia capabilities with circuit-switched calls

The present invention relates to a composite user agent acting on behalf of a group of member user agents in a communication network. The composite user agent provides its group of member user agents with a specialized proxy function while representing the group to the network as a single user agent. To devices on the communication network, the composite user agent behaves and is viewed as a user agent. To the group of member user agents, the composite user agent behaves and is viewed as both a registrar and a proxy server.
