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 personal user agent acting on behalf of a group of member device agents in a communication network. The personal user agent provides its group of member device 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 personal user agent behaves and is viewed as a user agent. To the group of member device agents, the personal user agent behaves and is viewed as both a registrar and a proxy server.

Personal user agent

An integrated telecommunication collaboration system which allows the close integration of desktop computer applications, data communications, and public switched telephone network voice connections. Client software which implements the invention includes a voice agent for establishing telephone sessions, a data agent for establishing associated data sessions, a communications agent which synchronizes the date and voice agents, and an integration agent which integrates the data and voice communications with a computer operating system, and with various applications. The integrated telecommunication collaboration system controls the establishment of harmonized calls by sending and receiving various requests and status messages to and from a server, and another client.
