PBX mobility system with multiple call legs
First Claim
1. 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.

Abstract
A private branch exchange (PBX) mobility system and associated method for re-using of call legs in an enterprise system. The enterprise system includes a session management platform (SMP) having a private branch exchange (PBX) mobility enabler, the PBX mobility enabler having third-party control communications to one or more PBXs over a session control interface, such as a Session Initiation Protocol (SIP) interface. The PBXs are in communication with one or more media servers. The PBX mobility enabler is configured to provide control communications to the PBXs over the session control interfaces to re-use a wireless call leg and connect to other call legs.

11. One or more servers configured for re-using of a first call leg, comprising:
-
one or more devices 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 one or more devices configured to provide control communications to the PBXs over the session control interface to; create 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 one or more devices, create a second call leg to a first destination wherein media terminates on one of the media servers and call control signaling terminates on the one or more devices, the one or more devices 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 create a third call leg to a second destination wherein media terminates on one of the media servers and call control signaling terminates on the one or more devices, the one or more devices 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. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. An enterprise system for re-using of a first call leg, comprising:
-
one or more media servers; one or more private branch exchanges (PBXs) in communication with the media servers; a session management platform (SMP) having control communications to each of the PBXs over a session control interface, the SMP configured to provide control communications to the PBXs over the session control interface to; create 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, create 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 create 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.
