Dubai E1 calls keep dropping

[Joemjauser]

Hello ,

I have a chronic problem with dropped calls in their Avaya gateway. It has a PRI. I know that when a call drops, the carrier can look at a record and see which end dropped it. Problem is, getting someone at the Dubai phone company to do that will be quite hard.

Is there a diag in the Avaya that can be run, hopefully after the fact, that shows which end dropped? Is there a field in CDR? (Doubt it). If not after the fact, what about an ongoing LI TRACE of the trunk group? Would the string show which end dropped in some sort of an ISDN code?

So far I checked that the Gateway is synced to the PRI, and that there are no errors on the circuit.

Thanks,
Joe

I used to work in Dubai and calling Etisalat is such a pain that you will be passed to different kind of person and there is no ownership for your E1 problem. You need to have the circuit ID information to have them BERT test your circuit to verify errors. How about try to troubleshoot from your end by trying Test Board 1vXX.And try to do a loopback in your E1 card and do the same test that you have done. Let me know if that helps.

Thanks!

What is the command for running a loopback test?

Try test board 1vxx, status signaling and status trunk x.

The board test shows "passed". The status sig shows "in service", and the stat trunk looks good.

Is there a way to verify real time or with reports which side is dropping the call? This problem continuous and I'm not certain what to do next.

Thanks everyone!
