I have 3 CCM servers, 1 publisher, and 2 subscribers. I also have 3 MGCP PRI gateways. Ideally I would like to register the gateways between my two subscribers so that if one sub failed not all the gateways would. The problem I am seeing is that my gateways will register to the publisher, and the primary subscriber just fine, but they will not register to my secondary subscriber. Initially this worked just fine, then we renamed, added, removed, and reconfigured our partitions and CSS. Once that was done we rebooted the CallManagers and then this happened. I have even tried adding a new gateway to the secondary subscriber without success. If i do a "show mgcp" on the gateways when they are pointed to the secondary subscriber, they say they are registered even though CCM says they are not, this I think is simply the keepalive/signaling port though and not a true registration. If anyone has any info on what I am seeing here I would really appreciate it, thanks alot in advance.
Your MGCP gateway shows that is registered to Cisco CallManager, but when you use an MGCP gateway in Cisco CallManager, sometimes it shows as unregistered in the Cisco CallManager Administration page.
Sometimes this can be because the Real-time Information Server (RIS) data collector service does not work as expected. Restart the RIS data collector service on the Cisco CallManager Publisher and Subscriber to resolve this issue.
Complete these steps to restart the RIS data collector service:
1. Go to the Cisco CallManager Serviceability page from Application > Cisco CallManager Serviceability.
2. Select Tools > Control Center.
3. Select the IP address of the server that should be restarted, then choose Cisco RIS Data collector and click Restart.
