[cisco-voip] 7970 Issue - phones constantly restarting/rebooting

Tue May 18 10:17:11 EDT 2010

I don't see anything there indicating a firmware download issue.  Your problem is that signaling packets are getting lost somewhere in the network.  If you just put these phones on a new switch stack I'd look hard a layer 2 issues in the stack.

All of the last= causes in those alarm messages indicate TCP sessions getting reset either by the phone or the CUCM.
