[cisco-voip] Many phones resetting spontaneously -- Traces?

[Tim Reimers]

I had to set up such an alert manually. Works pretty well, aside from
the fact that I don't get any sort of idea about which phones went down.
 
I'd like to get this:
"in RTMT you can do a device search for phones and include parts of the
IP address of the phones in question and you will see a column that has
the time the phones reconnected with CM"
 
as a history - not just the last time, but whether or not repeated
boot/register events are happening to just a few phones, or even just
one phone that I know I want to monitor.

RTMT Alert Central should have an alert when a large number of devices
unregister. Might give a timestamp on about what time to start looking
in ccm trace files, etc.

In General:

the traces actually say 'unregister' with device name.  If phones went
down enmass then typical approach is:
1. check CM system and application logs.  look for any critical system
events (cm crash/restart?)
2. pull CM SDI and SDL traces.  when phones next re-register they send a
reason code for the last unregistration in an ALARM message
3. parse traces to identify phones that *did* and *did not* unregister.
identify patterns in the groups of phones such as subnet, primary cm,
phone model, device pool, etc.

I got a report late this afternoon that a fair number of calls were
dropped when phones reset spontaneously.  All phones were registered to
a single subscriber.  I am trying to narrow down the cause of the event.
Unfortunately, nobody thought to record an accurate time when the event
occurred.  Thus, I have to dig through the traces (I don't see
unregisters in the Application logs).

What does an unregister look like in traces, or what else could I search
on that might identify the moment when this occurred?

If there is any additional info I can provide that would help, please
let me know.
