  • Lightweight internet protocol telephony client
    Publication number: 20030002478
    Abstract: An Internet Protocol (IP) telephony system includes a lightweight stimulus client configured to receive user input requesting an IP telephony service (e.g., an ITU-T H.450 supplementary service) and communicate the received input over a packet-based network using a standard call control protocol (e.g., Media Gateway Control Protocol or ITU-T H.248). A call agent, executing on a remote server connected to the packet-based network, is configured to perform the requested IP telephony service based on the received input.
