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

[John Todd]

So, I've managed to consistently lock up my Cisco 7960 (SIP 6.1) to 
the point where it needs to be unplugged, due to software errors. 
This is a first.

My suspicions are that this bug in Asterisk is causing the lockups:
   http://bugs.digium.com/bug_view_page.php?bug_id=0000889

It seems unusual to me that a low volume of bogus SIP messages should 
lock up the 7960, but that seems to be the case.   It seems this only 
happens on my 7960 that I have completely full of extensions (all six 
line buttons are lit, two of them are auto-answer.)   I think this is 
one bug tickling another bug; bad messages from * are killing the 
7960.

I'd like anyone else with experiences with this  type of failure with 
Asterisk to give me a shout; I'm going to report this to Cisco 
somehow, but don't have enough evidence.
