ABSTRACT:
A communication system in accordance with the present invention includes at least one network appliance device (3415) which is coupled to a network (3402). The network appliance device (3415) includes software for detecting incoming calls and initiating call sessions in accordance with a signaling protocol. The system further includes a wireless communication gateway (3410) coupled to the network (3402) for allowing the network appliance device (3415) to communicate in accordance with a wireless network protocol. The wireless communication gateway (3410) includes, or is coupled to, a communication proxy (3405) for translating messages between the signaling protocol and the wireless network protocol. In one exemplary embodiment the signaling protocol takes the form of the Session Initiation Protocol (SIP) and the wireless communication protocol takes the form of the Wireless Application Protocol (WAP).
