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 two minutes for a reply. If a reply is not received within the two minute
window, a protocol time-out violation will be recorded in the error log against the
associated signaling channel (ISDN-PRI Signaling Link Port, which is listed in the
Error Log as ISDN-LNK/ISDN-PLK; the Error Type is 1).

Result
ABORT Maintenance is disable on this trunk.
1. Enable maintenance by entering "y" in the "Maintenance
Tests?" field on page 2 of the change trunk-group form.
ABORT An audit is already in progress.
1. Wait two minutes and try again.
ABORT The signaling link has failed, so the system cannot send any
messages on behalf of this trunk.
1. Check the results of Test #255 (Signaling Link State
Check).
ABORT The signaling link is in a transitional state.
1. Retry the command at 1-minute intervals a maximum of 5
times.
ABORT The trunk is in an out-of-service ISDN service state.
1. 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 status trunk).
ABORT Could not allocate the necessary system resources to run this
test.
1. Retry the command at 1-minute intervals a maximum of 5
times.
