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.

Abstract: A system for providing and managing IP telephone calls establishes separate and distinct call legs between IP-capable appliances and routers and between routers, and creates calls, changes calls, and manages telephony functions by joining and disjoining calls legs. In some instances one or more call legs disjoined from an active call are maintained as established to be joined later to other call legs to create other active calls. By managing EP calls as separate and distinct legs functions of intelligent, connection-oriented telephony networks may be simulated in IP telephony systems. The management is provided by software running on processors coupled to routers in the IP network.

Abstract: A telephone switching and routing system has a first switching apparatus for receiving incoming calls, a first processor connected to the first switching apparatus, and a plurality of destination sites each connected to the first switching apparatus by a telephony trunk, each destination site including a destination processor coupled to the first processor by a communication link separate from the telephony trunk. The first processor connected to the first switching apparatus maintains a list of incoming calls received at the first switching apparatus as a virtual queue, wherein individual ones of the destination processors at the destination sites monitor local agent status and skill sets, and request switching of calls from the published lists as agents become available to handle new calls, and the first processor in response to requests from the destination processors controls the first switching apparatus to switch calls to the requesting destination sites.
