I am trying add a fax server. The vendor says the PBX must pass the DN as TDMF after the line is off hook. They also say that this is standard for all analog fax servers and analog voicemail servers. I currently have the server connected to four analog ports configured as 500 stations with cicular hunting using DTN.
How do I get the PBX to pass DTMF digits?
