I was eagerly planning to switch over from an aastralink PRO 160 system over to 3CX and was verifying that all features would be supported, but then I see one that looks like it does not. Currently our company only has a single external telephone # (with multiple lines as part of a hunt group). This number is published as both our voice and fax number. The aastralink will auto-detect if an incoming call is a fax (using the fax machines CNG tone). If it is a fax, it routes it to the fax machine. It works well. In looking at the 3CX documentation, it looks like I have to have a caller manually enter the fax machines extension or use DID (and have to publish to all clients that out fax number has changed, and change all of our literature). Does the 3CX system really lack they ability to discern CNG tones and route a call to the fax server or fax extension? 3CX system seems too feature-packed to be missing a feature like this. I must be missing something.
