1. A network implemented communication system, comprising:
- a Local Area Network (LAN);
a plurality of H.323 endpoints connected to said LAN, each of said endpoints including a communication application for communicating via H.323;
at least one H.323 Gatekeeper connected to said LAN for third party control of communications between said H.323 endpoints; and
software within each of said H.323 endpoints and said H.323 Gatekeeper for implementing features which do not require direct connection between said H.323 endpoints, wherein said software comprises a call control application in said Gatekeeper including a plurality of user software agents representing said H.323 endpoints, wherein said user software agents generate feature commands for receipt by respective device software agents in said call control application which in response forward said commands via H.323 communications to said H.323 endpoints, and a plurality of H.323 applications in each of said H.323 endpoints for implementing said features in response to receiving said feature commands.
