There are two primary reasons why devices will unregister from  
CallManager; one is high CPU utilization and the other is network  
related issues.  Capturing processor related perfmon counters will help  
determine if CPU is the issue.  Detailed CCM and SDL/CCM traces will  
help determine if the problem is network related.  Probably will need  
to gather packet captures too.

I have seen more cases where network issues are the culprit instead of  
CPU.  You might consider opening a TAC case to help diagnose the  
problem as it can be quite complex.
