I have a working set of sip trunks used as a tie to our fax server and all traffic to and from the server uses our PRIs. We have 24 sip channels provisioned for the server, but just 12 fax server channels. Periodically through the week we get a rash of faxes to our switchboard when they have obviously faxed to the correct number. I suspect that when our fax server's channels are busy, the calls are being routed to the switchboard. I would like this to stop and, instead, give the calling fax a busy signal. I can't find anything that addresses how to change this and I'm hoping someone here will know.
This isn't a massive inconvenience but it does delay the fax delivery to the department and as a hospital that's not good.
