Abstract

A telecommunications system according to an embodiment of the present invention includes a packet network; a first plurality of network clients compatible with a first voice protocol of the network; a second plurality of network clients partially compatible with the first voice protocol; a third plurality of network clients compatible with a second voice protocol; a gatekeeper adapted to provide call control for the first plurality of network clients; a feature proxy adapted to receive registrations of the first plurality, the second plurality, and the third plurality of endpoints, and map such registrations to registrations with the gatekeeper and provide feature processing for the first, second, and third plurality of endpoints.

Claims

1. A telecommunications system, comprising:

a packet network;

a first plurality of network clients compatible with a first voice protocol of said network;

a second plurality of network clients partially compatible with said first voice protocol;

a third plurality of network clients compatible with a second voice protocol;

a gatekeeper adapted to provide call control for said first plurality of network clients;

a feature proxy adapted to receive registrations of said first plurality, said second plurality, and said third plurality of endpoints that maps such registrations to registrations with said gatekeeper and provides feature processing for said first, second, and third plurality of endpoints.

2. A telecommunications system in accordance with claim 1, wherein said feature processing comprises supplementary service feature processing.

3. A telecommunications system in accordance with claim 1, wherein said feature processing comprises media stream feature processing.

4. A telecommunications system in accordance with claim 1, wherein said feature proxy is further adapted to implement CTI control of said endpoints.

5. A telecommunications system in accordance with claim 1, wherein each of said first plurality of network clients is mapped to a corresponding registration with said gatekeeper.

6. A telecommunications system in accordance with claim 5, wherein each of said third plurality of network clients is mapped to a single registration with said gatekeeper.

7. A telecommunications method for use in a telephony-over-LAN network, comprising:

receiving first registrations of a first plurality of network clients at a feature proxy;

receiving second registrations of a second plurality of network clients at said feature proxy;

mapping said first registrations to corresponding registrations with a network gatekeeper; and

mapping said second registrations to a single corresponding registration with said network gatekeeper.

8. A telecommunications method in accordance with claim 7, wherein said first plurality of network clients are compatible with a voice protocol of said LAN.

9. A telecommunications method in accordance with claim 8, wherein said second plurality of network clients are compatible with a different voice protocol.

10. A telecommunications method in accordance with claim 9, further comprising said feature proxy interworking said first plurality and said second plurality.
