[Asterisk-Users] cisco 7920 makes 7940 reboot

[Dan Adams]

Just a guess on 31, but have you made sure you have a different IP Number 
on each of the two phones. With some of my own observations in watching 
them boot up, I have remembered that even if it is assigned a static IP, 
it still has a phase that says "Obtaining IP"

Just a thought.
