Abstract

See full text

A particular method includes receiving a signal to invoke a central server-directed service from a first communication device at a session initiation protocol application device. The first communication device is coupled to at least one second communication device via a pathway of a half call model communication session. The method includes sending first instructions to the first communication device via the session initiation protocol device in response to the signal. The first instructions enable the first device to access the central server-directed service. The method also includes sending second instructions to the at least one second device via the session initiation protocol device in response to the signal. The second instructions enable the at least one second communication device to access the central server-directed service.
