Hi, We've had our 3CX system up and running for a few months now with a few minor problems. Now we're moving on to doing fax through 3CX. I'm looking for help in configuring this properly as we are getting nowhere on our own and with no support (company we bought the system from sucks). Our setup is this: 3 PSTN lines from telco -> GXW-4104 -> Network Switch -> 3CX Server and SPA-112 SPA-112 -> Analog Fax Machine (an old Brother unit) We only have 1 PSTN line with Fax enabled (line 1). Right now we are able to call the fax machine from our internal IP phones and from the outside. We have not been able to receive a fax yet and we are unable to make outgoing calls from the fax machine. Any ideas what may be the problem?
