Abstract
An SIP-H.323 gateway (210) is provided, which functions as a multi-alias H.323 endpoint (204) with one alias representing one SIP agent (206). The SIP-H.323 gateway (210) processes the call signaling conversions and stores and passes media port information to the signaling parties, so that the existence of SIP agents (206) is transparent to the H.323 endpoints (204) and the features are transparently available to the H.323 endpoints.
