Abstract
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 system, comprising:
- a cellular network including a mobile switching network and a carrier gateway server;
- and
- an enterprise network including an enterprise gateway server and a private branch exchange coupled therewith,
- wherein the enterprise gateway server is coupled with the carrier gateway server, and
- wherein the carrier gateway server receives, from the mobile switching network, a session origination request of a session destined to a mobile station and queries the enterprise gateway server for a policy,
- wherein the enterprise gateway server returns the policy, wherein the policy comprises enterprise session routing criteria applied to the session comprising at least one of a restriction on times the session may be routed and restrictions on destinations where the session may be routed,
