I had a customer call me up and tell me that one of his remote sites could not call out local calls. They wanted all long distance calls going out the HQ site and all local calls going out the remote site (appropriately). I set this system up a long time ago, so I had to refresh myself on their config. I found that MGCP was not communicating with the one remote site gateway. All other remote sites were OK. So here is what I did to verify, in this case.
I went on the voice gateway (which is just a Cisco router) and did a "show mgcp connection" after trying to make a test call. It showed nothing.
CLEVELAND#sh mgcp con
CLEVELAND#sh mgcp con
You see above, that I run this command twice. Nothing.
So I went into the CUCM and reset that particular gateway (not reboot the router, reset IN CUCM). I waited a few minutes and ran the command again after making a test call. Below is what I got:
CLEVELAND#sh mgcp conn

Cisco Voice: MGCP Connection Down To Your CUCM From Voice Gateway

Could you brief the options and tabs on CUCM to reset that gateway.ReplyDelete
I have a new user and got login on CUCM.
Be careful when resetting the gateway. I would suggest that if you are not sure where this is at in cucm, you may need to consult your primary admin of the phone system before taking on this task.Delete
