1. A method for integrating separate circuit-switched voice and packet-switched data sessions comprising:
- a. identifying call signaling events for a separate circuit-switched call between a caller and a called party over a circuit-switched network; and
b. controlling a separate packet-switched session for a packet-session between a caller user agent for a caller endpoint and a called party user agent on a called party endpoint based on at least one of the call signaling events from the separate circuit-switched call, wherein the caller and called party are associated with the caller and called party endpoints, such that the caller and called party may conduct concurrent voice and data sessions.

Abstract
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.

12. A system for integrating circuit-switched voice and packet-switched sessions comprising:
-
a. a communication interface; and b. a control system associated with the communication interface, the control system configured to; i. identify call signaling events for a circuit-switched call between a caller and a called party over a circuit-switched network; and ii. control a packet-switched session for a packet-session between a caller user agent for a caller endpoint and a called party user agent on a called party endpoint based on at least one of the call signaling events, wherein the caller and called party are associated with the caller and called party endpoints. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A computer readable medium with software for integrating circuit-switched voice and packet-switched sessions, the software embedded in the computer readable medium and comprising instructions for a computer to:
-
a. identify call signaling events for a circuit-switched call between a caller and a called party over a circuit-switched network; and b. control a packet-switched session for a packet-session between a caller user agent for a caller endpoint and a called party user agent on a called party endpoint based on at least one of the call signaling events, wherein the caller and called party are associated with the caller and called party endpoints. - View Dependent Claims (23, 24, 25, 26, 27)
