[cisco-voip] phone rebooting itself

More recent versions don't have them in the Admin guide but they are  
in the System Error Messages doc for each version.
http://cisco.com/en/US/docs/voice_ip_comm/cucm/err_msgs/7_x/ 
ccmalarms701.html (7.0)

Be aware though that this is just the reason that CUCM thinks the  
phone unregistered for and is pretty general (and not entirely  
accurate in some cases).  To  get a more accurate unregister reason  
you can look at the sccp alarm message the phone sends the next time  
it registers (most likely to the backup CUCM server or SRST router).   
In CCM traces search for the text "last=".  This is where the phone  
indicates the reason it last unregistered from CUCM.

As Jason mentioned if you've got phones losing connection to CUCM  
then you need to get a packet capture from behind the phone (and  
preferably at the CUCM for the same time period).  It really doesn't  
take long for newer phones to time out a TCP session if it is not  
getting TCP Acks from CUCM.

Unfortunately, it's from CCM 3.x, but unfortunately the more recent  
documents don't include the detail this one does.

Get a packet capture are the back of the phone after enabling Span to  
PC Port on the phone config page. That will definitively tell you why  
the phone unregisters.

Double check the requirements for phones across a WAN and make sure  
you within spec.

That's the first thing.

Second thing, test the reliability of your WAN link with a ping  
plotter tool of some type from HQ to the remote site. You may have a  
fast link, but if it goes down for whatever reason, for any period of  
time you'll see what you are seeing now.

The 7911s are even more susceptible to this (or more resilient,  
depending on your thinking) - they failover rather quickly.

I have a remote office that has 25 phones: 1 7975, 2 7965, and rest  
are 7945.
All the phones are connected to the WS-C3560-48PS-S switch.
I am using H323 on the Cisco 2811.

Problem: time to time phones reboots itself or disconnects from the  
call manager and gives below messages.
-UCB failure error
-certainly drops the call when they are on the phone
-it goes in to SRST mode(failover mode)-- it comes right backup.

I worked with Cisco TAC but they are saying the phone lost the  
connection to the Call Manager.
Why it loses the connection to the CM?
Maybe the switch is too small to support 25 phones?

Does anyone know what maybe the cause of the issue?

Thanks,

To add to what Bill said, for the port status monitor, make sure you
use the one from tools depot, not the web based one. The web based one
only shows you 'real time' state, where as the tools depot one has a
buffer and will show you the whole call, much easier to follow.

Something else you might consider is using the Audio Text Manager, it
helps to visualize your config and makes things a bit easier to
navigate when you've got a complicated tree:
