Hm :(

You say the USB ethernet adapter got unplugged and then reconnected...

1. What's the name of the network device for this adapter?  Is it the same 
name as it previously had?

2. What does 'ifconfig' say the IP address is for this adapter?

3. What do you have in /etc/asterisk/iax.conf for 'bindaddr' and 'bindport'?

4. Do you have SIP connections on the same network interface, and are those 
working as normal?
