Call to Non-Local Extension: Message from CO

2. If you are directly connected to the system where the destination
extension is located, go to Step 3. Otherwise, the coordinating
system manager should repeat Step 1 for each system through
which the call is routed until you reach the system where the
destination extension is located.
3. Check with the system manager at the destination system or with
the coordinating system manager to ensure that the extension
number is in the local dial plan for that system.
NOTE:
The system does not permit programming of non-local extension ranges
that conflict with extension numbers included in the local or non-local dial
plan. However, conflicts can still arise due to digit prepending or
absorption as a call is routed across the private network.
If this is not the problem, call the Lucent Technologies Helpline at 1 800
628-2888; consultation charges may apply.
Call to Non-Local Extension:
Message from CO
Possible Cause: If someone calls a non-local extension and connects to a
central office message announcing a misdialed number or some other problem,
the call is routed over a PSTN trunk (PSTN facility pools rather than tandem
trunk pools are sometimes assigned to secondary UDP routes such as Routes
3 or 4). Problems can occur when the programming for a PSTN route does not
at least prepend the correct digits (as in 555, for a local access call, or 1555 for
a toll access call prefixed before a 4-digit extension number) and possibly
absorb digits as well, in order for the call to be directed properly.
What to Do: Check the UDP range for the pattern to which the dialed extension
is assigned. See "Reviewing the Non-Local Dial Plan and Routing" in Chapter 6
of Network Reference for instructions.
