MGCP and PRI

Unanswered Question
Apr 16th, 2009

Hi,

We have a 2821 gateway with 2 PRI ports managed by CallManager 6.1 via MGCP. We had an issue earlier in the week that all trunks were busy due to a configuration problem on the PBX side. I wanted to find out which calls (calling and called numbers) are on which channel, but I could not find the command to see that information and I could not see it via RTMT either. Any help would be greatly appreciated! Thanks,

Yiwen

I have this problem too.

Hi Yiwen,

The gateway will not have the calling/called number to channel mapping since it doesn't inspect the Q.931 with backhaul enabled. This would need to be done somewhere in RTMT, which I admittedly don't play with very often.

From a gateway perspective I normally figure this out by matching the IP address of the phone against the 'show call active voice brief' output. This is mostly for troubleshooting and isn't very scalable however.
