We have a Patton SN4112 over which our company receives faxes over a PSTN line (FXO interface). The SN4112 passes the session to 3CX, which routes the incoming fax to an analog fax machine, itself registered with 3cx via a Patton SN4112 FXS device. The fax machines seems to receive a "TSID" from the sender, and prints it (the phone number) atop each inbound fax. I am wondering if 3CX is able to read or detect that inbound TSID. We would like 3CX to perform some logic on the incoming call, based on the TSID value. Thanks!
