ABSTRACT:
A telecommunications system and method is disclosed for providing call transfer services within H.323 networks, in which the transferring end-point that invokes call transfer relays the media packets received from the transferred end-point to the transferred-to end-point, and likewise relays media packets received from the transferred-to end-point to the transferred end-point. However, the transferring end-point is taken out of the call after transferring the call so that it can make/receive new calls.
