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.
Claims18
A method for re-using of a first call leg in a system, the system including one or more private branch exchanges (PBXs) in communication with two or more media servers, the method being implemented by control communications from the PBXs, 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;
- creating a second call leg to a first destination wherein media terminates on one of the media servers;
- connecting the respective media of the first call leg and second call leg together thereby establishing a first call session;
- creating a third call leg to a second destination wherein media terminates on one of the media servers;
- and
- connecting 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.
A system for re-using of a first call leg, comprising:
- two or more media servers;
- one or more private branch exchanges (PBXs) configured to provide control communications to the media servers to:
- create the first call leg to a wireless device over a wireless network wherein media terminates on one of the media servers,
- create a second call leg to a first destination wherein media terminates on one of the media servers,
- connect the respective media of the first call leg and second call leg together thereby establishing a first call session,
- create a third call leg to a second destination wherein media terminates on one of the media servers, and
- 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.
