Using www2 and registering with pbxes.org, I'm getting an all circuits are busy message on every trunk I have setup. I am however able to call directly between extensions. Anyone else currently have this problem?
I had the same problem this morning (woke up to my family complaining that they can't phone out.. again).
All I did was a "Personal Info" -> Submit & Start (essentially resets the PBX) and everything is working fine now.
I believe it has to do with the recent failures on the San Diego (www2) server.. somehow in the transition in moving accounts to the backup server (New York, www4) and back, the PBX stopped registering properly with the VoIP providers.
