Patent ID: 7729344

Claim:
A method, comprising: receiving a media signal at an interface device in communication with and disposed between an Internet Protocol private branch exchange (IP-PBX) and a first endpoint, the media signal being associated with the first endpoint and being associated with a session established between the first endpoint and a second endpoint within a session over internet protocol network, the session being established at least in part by the IP-PBX based on a session control signal received at the interface device from the first endpoint and sent from the interface device to the IP-PBX, wherein the interface device is separate from the first and second endpoints, the media signal and the session control signal being sent from the first endpoint via an IP network; modifying the media signal at the interface device based on a per-device service associated with at least one of the first endpoint or the second endpoint; and providing the modified media signal from the interface device to the second endpoint in a manner that bypasses the IP-PBX.
