I am stumped on this one... A fairly new PIAF installation, still not even fully in-use but all phones are deployed on our desks. For testing, everything has been going smoothly until today...
The internet connection went down, so of course our outbound VoIP route would not work any more, which I knew would happen, but what I didn't expect was that it killed our in-house system.
All of the phones started to randomly display "No Service" at various intervals. Looking at asterisk, the box was idling, and the logs showed that occasionally it would register the extensions again until they dropped.
All configurations that I could find are all set to use IP address only, so I can't imagine that DNS issues are at play. Just to verify, I changed our internal DNS server to provide forward and reverse entries for all the phones and the pbx system.
Ping times on the network were fine, no packet loss or other oddities, from various systems or from the PIAF pbx system to the phones.
However, still getting lots of service loss messages between phones and the server.
Then, the internet connection came alive again, and all of a sudden everything works great.
Anyone know what this could be? All the phones are Aastra 57i models and we are using the XML Scripts package, is it doing something requiring an internet lookup or something that was timing out? I'm really at a loss here. Using lsof didn't show any weird outbound connection attempts, but I could have missed it and didn't do extensive packet sniffing.

But we do have some SPA3102's in use, so I just renamed their trunk so they are before Callcentric and it seems like this will solve the problem. I would test it now, but surely the users would revolt if I pulled the plug on their internet again.
