	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” on page 3 for instructions.

If there is no error in the local programming and there is an intervening system between yours and the system where the destination extension is located, speak with the coordinating system manager. The coordinating system manager should check the intervening system’s UDP tables for proper digit manipulation. He or she can determine whether the routing problem is on that system.

If this is not the problem, call the Lucent Technologies Helpline at 1 800 628-2888; consultation charges may apply.

Transfer to Non-Local	6
Extension Not Completed

There are several possible causes for an incomplete transfer. They are very easy to check.

Do Not Disturb. Calls transferred to non-local extensions that have Do Not Disturb active, using tie tandem trunks, do not return and the caller hears busy. The exception is a transfer that is routed over PRI tandem trunk that is manually completed. In this case, the transfer returns as an incomplete transfer.

Transfer from PassageWay Telephony Services Client. Transfers with consultation cannot be made from PassageWay Telephony Services clients to non-local extensions. The user must make such a transfer by using a telephone.

NOTE:

PassageWay Telephony Services clients cannot use an application to transfer calls across the private network. The user must make transfers manually using a telephone. If the transfer recipient is a PassageWay
