ABSTRACT:
The present invention provides a combined user agent (CUA) to represent a telephone supported by a circuit-switched telephony switch and a packet-based media device as an integrated group to other network entities. The CUA is configured to facilitate the necessary call signaling to establish and control a voice call via the telephony switch, as well as the session control signaling necessary to establish and control a media session with the media device. Accordingly, the telephone and media device appear to the network devices as a single device having voice and media capabilities, wherein the voice capabilities are controlled in part by the telephony switch.
