ABSTRACT:
The inventive method uses a VoIP server which provides the classical subscriber performance features of an exchange, and a VoIP client in the integrated access device (IAD) of the subscriber. The VoIP server uses a known VoIP signalling protocol for controlling the VoIP voice transmission between the VoIP client in IAD and the media gateway and for tunneling the PSTN/ISDN signalling between the VoIP client in the IAD and the VoIP server.
