2.16.2 Automatic Fax Transfer
Description
The PBX can distinguish between fax calls and other types of calls arriving on DISA lines, and automatically
transfer fax calls to preprogrammed destinations. When a call arrives on a DISA line, an OGM is played
(® 2.28.2 Outgoing Message (OGM)). At the same time, the PBX begins fax signal detection. If a fax signal
is detected, the PBX recognises that the call is a fax call, and transfers the call to the fax destination assigned
to that OGM through system programming. This allows a single trunk to be used seamlessly for both voice and
fax calls, with only voice calls arriving at user extensions.

A PS destination can be used to forward fax calls to a fax machine at another PBX connected by TIE line.
A virtual PS can be specified as the destination of fax calls. Then, the extension number of the fax machine at the other PBX can be
specified as the FWD—ALL Calls destination for calls to that virtual PS. (® 5.2.4.6 Virtual PS)
Conditions
• This feature is only effective for calls arriving on DISA lines.
• If a fax signal is not detected before the DISA Intercept Routing—No Dial timer expires, the call is redirected
to the operator extension, and fax detection ends.
• If the fax tone (CNG signal) detection is delayed because of the fax machine type or the state of the line,
the DISA intercept timer may time out and the fax cannot be received. In this case, increasing the DISA
intercept timer by 5 to 10 seconds will help avoid this problem.
