A process and apparatus to facilitate communication between callers and callees in a system comprising a plurality of nodes with which callers and callees are associated is disclosed. In response to initiation of a call by a calling subscriber, a caller identifier and a callee identifier are received. Call classification criteria associated with the caller identifier are used to classify the call as a public network call or a private network call. A routing message identifying an address, on the private network, associated with the callee is produced when the call is classified as a private network call and a routing message identifying a gateway to the public network is produced when the call is classified as a public network call.

A method of establishing a communication link between a mobile terminal of a wireless network and a subscriber of a network, such as an enterprise network, and/or a residential network.

A method of operating a network server, such as a mobile application gateway, connect devices on a cellular or carrier network with individual networks, such as enterprise voice and data networks or residential networks. The effects of the present invention are far reaching in terms of transferring effective call control from the cellular network into the control of the individual network, such as the enterprise, and enabling new business models for the purchase of cellular service from a public cellular carrier by an enterprise.

A method, apparatus and system for routing a communication in a communication system between a first participant device, on an Internet Protocol (IP) network, associated with a first participant, and a second participant device associated with a second participant. The method comprises receiving a second participant identifier associated with the second participant device, causing the at least one processor to access a user profile that is specific to the first participant and associated with a plurality of first participant attributes, comparing the second participant and at least one first participant attribute and identifying whether at least one route exists, producing route information to an Internet Protocol (IP) address on a first communication network or associated with a gateway to the second communication network, and establishing the communication to the second participant. At least one of the networks may utilize Public Switched Telephone Network (PSTN) compatible numbers for identifying a route for the communication.

A system, server, and method of DTMF detection in a VoIP network.
