Abstract
A call control system to route a voice over internet protocol call between a wireless communication device and a destination device comprises a communication interface and a processing system, wherein the destination device is located in a geographic area served by a communication network. The communication interface is configured to receive an authorization response from an authorization system located in a home wireless network of the wireless communication device, wherein the authorization response comprises a destination identifier of the destination device and a location identifier of the wireless communication device. The processing system is configured to process the destination identifier and the location identifier to determine if the wireless communication device is located in the geographic area, and if so, the processing system is configured to direct the communication interface to transfer the call over a source port associated with the geographic area served by the communication network.
