TEL/FAX mode
(automatic voice and fax recognition)
Use this mode when you wish to receive voice calls with rings, but do not want to hear the unit ring when
faxes are received.
When a call is received, the unit will work as follows:
A call is received.
The unit will automatically answer the line without ringing.
(At this point, a telephone fee will be charged to the caller.)
¡ If a TEL/FAX greeting message is recorded (see page 43), it will be played to the caller.
If extension telephones are connected, only they will ring before the call is answered. \
The unit will now distinguish between a voice and fax call by detecting the calling tone.

manually.
