[Asterisk-Users] Asterisk Causing Cisco 7200 Router to Crash?

[Brian Wilkins]

A traceback is not possible. The best thing I can show everyone is the reboot 
message. The logs got obliterated when the Asterisk server started up and the 
best we can imagine, sent an invalid "code" to the router. We are going to 
set up a small test subnet here and bounce around on the router to see what 
is the problem. The Cisco 7200 router uses the IOS that is optimized for 
VoIP. The server caused our fiber card to burn up and now we have to replace 
it.
