CCM lost the MGCP control of the Gateway - DMVPN Circuit

Hi All,

We have a remote office with a mgcp gateway [ 2800 Software (C2800NM-ADVIPSERVICESK9-M), Version 12.4(24)T ] registered to Cisco Callmanager 4.1.3 thru a DMVPN connectivity.

The Callmanager is losting the control of the PRI two times per week...so inbound and outbound calls has been affected, do you have ny insight on this error? 

Thanks in advantange!

Re: CCM lost the MGCP control of the Gateway - DMVPN Circuit

I used to have this same problem so I converted all my remotes to H323. Backhauling a D channel across the WAN always seemed to introduce more problems than it was worth. While MGCP is easy to use, H323 is far more flexible and once you get used to it you will love it. Just my two cents on your problem. TAC simply blamed the network while running MGCP so they were no help.

Good Luck!

Thanks Tracy!

However I found something that I don't have configured (in red) maybe can help. Did you try with this before to go H323?

Unfortunately that is the first thing the TAC played with but maybe you will have better luck than I did! Good luck to you!
