Should the controllers be set back to "service mgcp"
06-20-2005 10:26 AM
Try to set the controller t1 back to service mgcp, "pri-group timeslots 1-24 service mgcp"
Let me know how it goes.

Found out after some digging, that the problem was not with the MGCP config in the router, but the FQDN in the CallManager. Reconciled the differnce, all returned to service.
It is always the little things.....

If you want to use MGCP and you want to use the ccm-manager configuration, you will need to modify the d-channel as well.
First, put the service mgcp back into the controller configurations.
Next, in the d-channel config Serial 0/0:23 and Serial 0/1:23, add the following line:
"isdn bind-l3 ccm-manager"
This backhauls the d-channel back to the CallManager (MGCP only!).
I also like to use these options, but they are not required.
ccm-manager config-server CALLMANAGER_IP_ADDRESS
ccm-manager config
