Abstract

A communication system for an organization having multiple sites uses a dual-mode device capable of both cell phone communication and telephone communication on a local area network (LAN). IP LANS are established at organization sites such that a temporary IP address is assigned to a dual-mode device that logs onto an organization LAN, and the IP address is associated at a PSTN-connected server on the LAN with the cell phone number of the communication device. The IP server notifies a PSTN-connected routing server when a device logs on to a LAN, and also provides a destination number for the IP server. Cell calls directed to the device are then redirected to the IP server and directed to the device connected to the LAN.

Claims

1-18. -18. (canceled)

19. A system for telephone communication, comprising:

an Internet Protocol (IP) IP network including an IP telephony server having a trunk connection to a public switched telephone network (PSTN);

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-network, and for receiving and sending audio data over the IP-network;

a routing server having a data network connection to a public switched telephone network (PSTN);

wherein the IP telephony server, upon connection of the dual-mode communication device to the IP network, 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 network to the temporary IP address.
