18. 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 associated with an enterprise network and queries the enterprise gateway server for a policy, wherein the enterprise gateway server stores information related to the session including the final destination and returns a policy to the carrier gateway server and routing instructions based on 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, wherein the enterprise gateway server enacts the at least one policy and the session routing criteria responsive to an enterprise user account access operation, wherein the enterprise gateway server provides routing information to the mobile switching network via the carrier gateway server for routing the session to the private branch exchange, the routing information comprising destination information and session path information for routing the session to a destination, and wherein the session is routed to the private branch exchange by the mobile switching network. - View Dependent Claims (19, 20)
