Call To Non-Local Extension Reaches Wrong Extension - Avaya MERLIN MAGIX Maintenance And Troubleshooting Manual

Maintenance and Troubleshooting
If the destination extension can be dialed directly via Direct Inward Dialing (DID) or PRI dial-
I
plan routing, try calling the destination extension over public switched telephone network
tandem 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
I
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 private network coordinating system manager and explain the situation.
Call to Non-Local Extension Reaches Wrong
Extension
Possible Cause: If a call to a non-local extension connects to the wrong extension, one or more
non-local dial plan extension ranges and/or routes may be incorrectly programmed. Non-local dial
plan numbers must be unique and unambiguous or calls can be misrouted. Furthermore, digit
absorption and prepending for the routes must be programmed correctly.
What to Do: First, review the local routing for the call. See
and Routing'' on page 5-11. Then follow the steps below.
1. At your local system, ensure that routing for the destination extension specifies pools of trunks
connecting to the correct adjacent system (if there is more than one). If digit prepending or
absorption is needed, make sure that it is correctly programmed. If you find an error, you have
solved the problem. If not, proceed to Step 2.
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.
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 Technical Support Organization at 1 800 628-2888; consultation
charges may apply.
