Trying to get inbound fax working with IPComms (claims to support T38) and 3CX. We've got a DID dedicated and everything setup properly to route the call. When we try to FAX or call the DID from any external source, we hear an outbound FAX tone from the 3CX system, instead of the receiving "warble" you normally hear from any FAX machine that's going to receive. I've found another use who had this issue, but have not been able to find any resolution. We're using an older version of the system (v8) so I'm not sure if it's broken in that version and was never patched, or if this issue still occurs in the latest version. Looking for any tips as we'd love to dump our local phone line dedicated to receiving FAXes and go with the VOIP line.
