The SIP routing system finally routes the SIP registrations to Call Server. The SIP responses are routed by the SIP routing system by using the same Subscriber/Server Flows that were matched during request processing.
Note:
After the remote worker registers successfully to Call Server through the Avaya SBC, subsequent registrations reuse the same Subscriber/Server Flows that were matched during initial SIP registration. Subsequent registrations reuse the same Subscriber/Server Flows until the remote worker deregisters from Call Server.
