[cisco-voip] Calling Party Number not showing up on some carriers sets (most of the time)

[Matthew Loraditch]

I use it all the time with no issue. It's a fantastic for troubleshooting. debug isdn q931 is all you need.

I usually do with a term mon so I can see the calls as I am dialing them. My customers volumes are much smaller than what yours probably is so I'm not sure if that would have any effect either cpu wise or making it harder to watch the live debug.

I'd like to try out this debug q931 stuff...

I can push calls out to a particular 3845 gateway.

Is debugging q931 stuff process intensive?

Is "debug isdn q931" all I need?

Did you debug q931 and compare legacy pbx to cisco cm outputs?

OK, here's a weird one.

We have had complaints about calls from our campus showing up as Unknown to a certain (Rogers) carrier.

I've done some testing and can replicate the problem using different phones, different gateways, different telco providers (Telus, Bell), etc. All show the same results. Unknown to Rogers customers, but the correct number to other carrier customers (Bell).

The one anomaly is when an outbound call is placed from one of our legacy PBX phones which are connected to our Cisco system via T1/PRI. Calls from these phones have the correct calling party number displayed on Rogers clients phones.

I've tried to replicate (albeit one at a time) any difference between the call routing from the HiCom vs the IP phone and no difference in the outcome.

Anybody have any clue what might be causing this?

My first thought is that it is a Rogers issue, but the fact that we are sending the number out for a particular group of users and it works fine has me thinking. Could the calls be marked slightly differently and this difference is not recognized by Rogers?

The problem only started happening a few months ago.
