Call State Audit Test (#257) - Avaya G350 Maintenance Manual

Call State Audit Test (#257)

If a call is active on the trunk, the switches on both sides of the connection should agree on the ISDN
state of the call, as defined in the ISDN Protocol Specification. This test audits internal call state data by
querying the far-end switch as to the ISDN state of the call. It can be helpful when trying to clear a hung
call. If the internal call state data on the near-end switch is different than that of the far-end switch, then
the call will be torn down.
As with Test #256 (Service State Audit), a PASS simply means that an appropriate message was
composed and sent to the far-end switch. The ISDN Specification allows up to 2 minutes for a reply. If a
reply is not received within the 2 minute window, a protocol time-out violation will be recorded in the
error log against the associated signaling channel (ISDN-LNK, Error Type 1).

Description/ Recommendation
Maintenance is disable on this trunk.
Enable maintenance by entering "y" in the "Maintenance Tests?" field on
page 2 of the change trunk-group form.
An audit is already in progress.
Wait 2 minutes and try again.
The signaling link has failed, so the system cannot send any messages on
behalf of this trunk.
Check the results of Test #255 (Signaling Link State Check).
The signaling link is in a transitional state.
Retry the command at 1-minute intervals for a maximum of 5 times.
The trunk is in an out-of-service ISDN service state.
A call cannot be present if the trunk is in an ISDN out-of-service state, so a
call state audit would be inappropriate. No action necessary. (Use the
status trunk group#/member# command to investigate the ISDN state of
the trunk).
Could not allocate the necessary system resources to run this test.
Retry the command at 1-minute intervals for a maximum of 5 times.
