A third generation (3G) gateway provides the facilities for extending a number of internet protocols between a second generation (2G) network and a 3G network. The various messages of a session initiation protocol (SIP) are extended to provide user identification and server identification subfields. The SIP message extensions facilitate the communication of 2G and 3G networks for the purposes of implementing push-to-talk and dispatch service features.
