Calls to Non-Local Extensions: Unexpected Busy Tone

Check that the routes voice/data capability is correct for the type of call
being made. The factory setting is Both, which will support both voice and
data calls.
In each intervening system, compare the FRLs assigned to routes for the
call with the default COR FRL. The route FRL must be equal to or lower
than the default COR value or the call is blocked. The factory setting is 3.
If FRL settings are not the cause, call the Lucent Technologies Helpline at
1 800 628-2888; consultation charges may apply.
Calls to Non-Local Extensions:
Unexpected Busy Tone
This topic discusses unexpected busy tones that may be caused by system
features. It applies not only to regular calls from one network extension to another
but also to remote access calls that are routed among network systems.
Possible Cause: Intersystem callers may receive a busy tone that is unexpected
because they know that the call recipient has coverage. However, in a private
network non-local calls are treated as outside calls by the system. The non-local
extension may not have coverage for outside calls turned on.
What to Do: Depending upon how the non-local system is set up, try one of the
following techniques in order to reach the extension:
If the destination extension can be dialed directly via Direct Inward Dialing
(DID) or PRI dial-plan routing, try calling the destination extension over
public switched telephone network trunks. If you receive the same busy
tone, then the Coverage setting may be the problem. Call the system
manager or receptionist at the non-local system and have them check the
extension to ensure that coverage is correct and that the extension is
functional.
If you cannot dial the extension directly, use public switched telephone
network facilities or the non-local dial plan in order to reach the operator for
the non-local system. Have the operator transfer you to the extension. You
should be able to leave a message for the extension user with voice mail or
with the operator.
If neither of the above methods solves the problem, call the non-local system's
system manager or the network coordinating system manager and explain the
situation.
