I have found Asterisk is terrible with any kind of internet outage. IAX 
stops trying to register if the internet goes down for a few minutes and 
the customer looses long distance calling until a tech resets the PBX. I 
had to setup a cron job to reload asterisk every hour to get any kind of 
reliability.
I also found the same problem with local calls, when I lose internet the 
locals calls go out also. How can that make any sense?
