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 mobile application gateway configured to interconnect mobile communication devices on a cellular network with an enterprise network is provided. The mobile application gateway includes a voice and data signaling gateway configured to provide routing functionalities, service functionalities and admission control. A gateway GPRS support node (GGSN) is configured to establish a secure data session between one or more of the mobile communication devices and the enterprise network by establishing a GPRS tunneling protocol (GTP) tunnel between a carrier-hosted serving GPRS support node (SGSN) and the GGSN.

Novel tools and techniques are provided for implementing originating number or address -based route determination and routing. In various embodiments, a computing system may receive, from a first router among a plurality of routers in a first network operated by a first service provider, first SIP data, the first SIP data indicating a request to initiate a SIP-based media communication session between a calling party at an originating address in an originating network and a called party at a terminating address in a terminating network. The computing system may determine a communication route among a plurality of routes through the plurality of routers in the first network for establishing the SIP-based media communication session, based at least in part on the originating address, and may establish the SIP-based media communication session between the calling party and the called party via the determined communication route.

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

An improved system and method are disclosed for peer-to-peer communications. In one example, the method enables an endpoint to engage in a call with another endpoint using a third party instant message system to carry instant messages containing signaling information and a route that is external to the third party instant message system for both signaling and media information.
