We have an AsteriskNow setup that seems to have been working just fine until recently. The problem that we have suddenly run into is that out of the blue all the inbound/outbound calls will tell us that all circuits are busy. The only way we seem to be able to get everything up and running again is to reboot the entire server. The error logs show “chan_dahdi.c: No D-channels available!” just before we notice that the phone system goes down.
Does anyone know what could be causing this problem? It is very frustrating because the system will randomly go down every few days.
