Which Trace Files to download from RTMT to determine unregistered phones at a specific time.

[jamize]

We received an RTMT alert early this morning that a percentage of phones had unregistered.  Unfortunately no one saw the alarm until later.  By the time we checked RTMT we couldn't see that many devices unregistered.  I'm trying to determine which trace files I can download from RTMT for that time (1:06am) to determine which devices went down.  I tried downloading the Call Manager traces but it didn't show any unregistered during that time.

Thanks,

Jeff

Hi JB - That's good information, however, I'm just trying to figure out which trace files to download t to determine which phones unregistered at 1:06am.  I'm not opening a TAC case for a severe issue. 

Do you happen to know which files would should that for a specific time?

Thanks,

Jeff

Hi Jeff,

For phone unregistration issue you can collect

Detailed Cisco Call Manager traces

Event Viewer - Application and Event Viewer - System logs

they should be able to provide all required information

Thanks JB.  I was able to find what I needed by pulling the last files you mentioned.
