That's a result of something else going on with the PRI, or caused by something going on with MGCP perhaps.
What version of CCM? Can you post the controller and serial interface portions of config, as well as MGCP and ccm-manager portions? If you're not using all the timeslots do you have the Change B-Channel Maintenance Status field set under call manager service paramters for this endpoint so all timeslots aren't used?
How often does this happen? run 'debug mgcp packet' to syslog or buffer when it happens. Also CCM detailed traces so you can see what ccm side is doing at time. On the debug, you may want to disable console/monitor logging and increase the buffer if there is a lot going on, or log it to a syslog server. A lot of debug traffic can have negative impact on router.
Also, post 'show ccm-man' output. That will give some stats for ccm-manager (last failover time, config download info, etc).
I believe 12.3.14T2 is also deferred, and current is 12.3.14T5. I've ran into several issues with MGCP in 14T and 12.4 so there may be a IOS issue perhaps but to early to tell for sure.

No. You will only need the SRST licenses on the primary router. Because this feature...
