Calls not forwarding???

[phonesaz]

I have a customer who has 2 copper lines with no hunting and a PRI T1. Both the copper lines are provided by Qwest, and the PRI is with Integra. These lines are main published numbers for 2 separate divisions of the same company.

Each morning the lines are separately forwarded (using the *72 and *73 feature from Qwest) to two separate DID numbers. xxx-xxx-0133 is forwarded to ext 556, and xxx-xxx-3500 is forwarded to ext 504. Both of these are physical extensions, but are primarily answered by other backup personnel, who answer the phones by means of coverage buttons on their phones. The people who cover 556 are not the same people who cover 504.

Here is my problem - the 556 group operates flawlessly. The 504 group does not. Most of the calls ring once and then disconnect, or ring once and go to a fast busy. This only happens when it is forwarded to the DID number. If you forward it to a cell phone, the first call gets answered and the second call goes to the cell phone voice mail.

I have bypassed the phone system to forward, unplugged the xxx-xxx-3500 from the phone system after it was forwarded, have had Qwest reprogram it, and it still happens.

I activated SMDR so I could watch calls. Not much help, except for it seems that several times a day calls to trunk 825, which is the xxx-xxx-3500 number, are acknowledged by the system as an incoming call with a duration of 1 second, but don't complete to anywhere.

Any suggestions on further troubleshooting or ideas about what could be calling this would be GREATLY appreciated. Thanks!

If you are utilizing cover buttons, I assume x504 is an extension on the system. I would do a print of that extension to see if there is any forwarding activated by accident (or something else). Maybe it is forwarded off-site without trunk to trunk enabled causing the line to ring once, try to forward, then go to fast busy. The print should hopefully make it obvious though.

yes - I have done a print and there is nothing. I just printed all the extensions that have primary cover appearances for 504 to see if there is anything there that could be causing coverage problems - there are a couple of glitches like one phone isn't in cover group 30 and another one covers to a third phone - I will fix those in the AM and see if it makes a difference -

It sounds like the line card port that's associated with 825 is whacking out. I've that behavior before, but only on 412 TDL boards. I've also seen failing 412 TDL ports trigger phantom ringing.

How about moving the POTS from 825 to another port? Or better yet, swap POTS line cords at the switch and see if the problem follows 825 (with xxx-xxx-0133 tied in for the test).

I shall try that this AM - see what happens.
