Patent ID: 8208931

Claim:
A method for re-using of a first call leg in an enterprise system, the enterprise system including a session management platform (SMP) having control communications to one or more private branch exchanges (PBXs) using third-party call control over a session control interface to each PBX, the PBXs being in communication with one or more media servers, the method being implemented by control communications from the SMP to the PBXs over the session control interface, the method comprising: creating the first call leg to a wireless device over a wireless network wherein media terminates on one of the media servers and call control signaling terminates on the SMP; creating a second call leg to a first destination wherein media terminates on one of the media servers and call control signaling terminates on the SMP, the SMP utilizing third-party call control of the media servers to connect the respective media of the first call leg and second call leg together thereby establishing a first call session; and creating a third call leg to a second destination wherein media terminates on one of the media servers and call control signaling terminates on the SMP, the SMP utilizing third-party call control of the media servers to connect the respective media of the first call leg and third call leg together thereby establishing a second call session, wherein an additional call leg to the wireless device is not created.
