Abstract:
A system for telephone communication, comprising:an IP-LAN including an IP telephony server; a dual-mode communication device comprising a first communication interface having circuitry for receiving and sending audio data on a cell-phone network, including a cell-phone number, and a second communication interface having circuitry for connecting directly to the IP-LAN, and for receiving and sending audio data over the IP-LAN; a publicly-switched telephone network (PSTN) having a trunk connection to the IP telephony server; and a PSTN-connected muting server; wherein the IP telephony server, upon connection of the dual-mode communication device to the IP-LAN, assigns a temporary IP address to the connected device and informs the routing server of the connection and a destination number of the connected device and wherein the routing server then routes calls for the cell phone number to the IP telephony server, which in turn routes the calls on the IP-LAN to the temporary IP address.
