I am having this issue with 3 completely separate systems in different locations. The thing in common is that I set them all up. This is probably a configuration issue, or something that I am not understanding. It seems like outbound calls work all of the time, however inbound calls work some of the time and then the caller gets a busy signal and I receive a CHANUNAVIL error from Vitelity. There are anywhere from 1 to 5 DID’s coming in the same trunk and routing to the same ring group if that matters.We want all of the DID’s that come in to go to the same ring group.
Sip Settings Outgoing:
Sip Settings Incoming:
The inbound route just sends everything to a ring group that has a few phones in it.
I am not really sure what to do, or look at next. Any help would be appreciated.
