IDP ReleaseCall (CAP1 Call) - Subscriber not Found

This example shows the message sequence used for a voice call using the CAP1 protocol in which MATRIXX Engine returns a TCAP Continue (ReleaseCall) message to the MSC to release the call.

Figure 1 shows the message sequence used for a CAP1 call when the subscriber cannot be found in the MATRIXX database, and MATRIXX Engine sends a TCAP Continue(ReleaseCall) message to the MSC to release the call. MATRIXX Engine also returns a TCAP Continue(ReleaseCall) if, for example:
  • The subscriber has run out of funds.
  • There are too many redirects.
