[Asterisk-Users] Cisco 7960 bug in 6.1 evident in Asterisk

[John Todd]

I had a previous error where, due to a faulty switch port, one of my 
7960's was rebooting or locking fairly often.  That was due to a 
physical, electrical error.

This problem is significantly different.  A fully-loaded (all six 
lines) 7960 will gradually stop registrations to one of my (distant) 
servers, and will often wedge itself, requiring reboot by power cord 
yanking.  Or it will spontaneously reboot.   I think this is due to 
some unusual SIP messages being sent to the phone from *, tickling a 
different bug in the phone that causes it to lose it's mind.  See my 
bugnote:

Due to other network conditions (i.e.: the remote server 3300 miles 
away has a cable modem problem) I am unable to get more details.
