[cisco-voip] Phone resets after upgrade

[Lelio Fulgenzi]

Have you checked that there is no IP address conflict? Also, what is the phone's perspective on why the reset happened? That is: Settings > Status > Network Statistics. On the third line you should see a code of sometype. Here's something I cut/paste a while ago. Not sure how up to date this list is.

a.. Failback-phone closed due failback to a higher priority Cisco CallManager. 
a.. Phone-Loading-phone closed to upgrade software. This message appears only if TFTP fails during software upgrade. 
a.. Phone-Keypad-phone closed due to a **#** reset. 
a.. Phone-Re-IP-phone closed due to a duplicate IP address condition. 
a.. Reset-Reset-phone closed due to receiving a Reset/Reset from Cisco CallManager administration. 
a.. Reset-Restart-phone closed due to receiving a Reset/Restart from Cisco CallManager administration. 
a.. All-CMs-Bad-phone detected a state in which all Cisco CallManager servers failed their keepalives. 
a.. Phone-Reg-Rej-phone closed due to receiving a registration reject. 
a.. Phone-Initialized-phone has not experienced a connection close since the hardware reset or since it was powered on.

  We recently upgraded to CCM 4.1(3)sr3a.  We have 2 phones (that we know about!) that reset multiple times each day and drop the call.  One is a 7960 and one is a 7940.  We have talked to Cisco TAC multiple times, but are still having the same problem.  They both have multiple lines, but a lot of the other phones that work normally do as well!  We have applied the TAC recommended patches on CCM and the phones (firmware), we've capture packets and sent the data to them for analysis, etc.  These users are getting very frustrated since they never know when the phone will reset.  It seems to always be while the phone is active (during a call).  We have moved the phones into a different powered switch, deleted them and added them back, replaced the 7940 phone itself - but, it is still happening.  I'm glad it's only 2 phones, but why??

  Does anyone have any ideas before these users become violent!!??

  Thanks.
