Call State Audit Test (#257)
This test audits the internal call state by asking the far-end switch for the ISDN call
state. The test is particularly useful when you are trying to clear a hung call. If the
internal call state on the near end differs from that on the far end, the call is torn
down.
The ISDN specification allows up to 2 minutes for a reply. If a reply is not received
within the 2 minute window, the test logs a protocol time-out violation against the
associated signaling channel (ATM-DCH, Error Type 1).
NOTE:
PASS simply means that an appropriate message was composed and sent
to the far-end switch.
