Abstract:
A method for operating a communications interface system, the method comprising:receiving an initial address message for a call into a circuit process and transferring the initial address message to a call process; processing the initial address message with the call process to generate set-up information and transferring the set-up information to a bearer system; receiving user communications for the call into the bearer system and routing the user communications in response to the set-up information; receiving a release message for a call into the circuit process and transferring the release message to the call process; processing the release message with the call process to generate tear-down information and a disconnect message, transferring the tear-down information from the call process to the bearer system, and transferring the disconnect message from the call process to the circuit process; generating a release complete message in the circuit process in response to the disconnect message and transferring the release complete message; and terminating the routing of the user communications in the bearer system in response to the tear-down information.
