automatically before it is answered. This mode can be enabled with one of the following automatic
detection modes.
Automatic answer mode
This mode answers with a tone or voice message recorded by the user and looks for fax tone to
determine if it is a fax call. If no fax calling tone (CNG tone) is detected within 5 seconds of the end
of a message, or the fax detector is busy on another call, then a normal incoming general call will be
generated.
Note: Older fax machines may not send CNG tone and therefore there may be a certain
number of ‘silent’ incoming fax calls which need to be transferred manually to the fax machine.
This is not a limitation of the telephone system.
The automatic fax answering service may be set up in parallel with any of the automatic
answering services, on page 31.
To record an answer message refer to ‘Voice Message Programming’ on page 58. An
appropriate message would be ‘If you are sending a fax, please press send now, otherwise please
wait to be connected.’
The number of rings before auto-answering is programmable, but it is recommended to keep
this setting at its minimum as some fax machines timeout after 30 seconds without a response
from the receiving fax.
Monitor mode
In this mode, the call will initially be handled as a normal call. If a fax tone is detected at any time up
to 45 seconds after the call is answered then the call will be automatically transferred to the
nominated fax extension. The person answering the call will hear busy tone when the fax call is
switched to the fax extension.
If an extension is designated as a fax extension (i.e. where the fax machine is located) then the system
will not ring this extension on normal incoming exchange line calls or internal code calls. The fax
extension must be nominated before programming the fax detection mode for the required
extension.
Set the fax machine to answer immediately or after 2 rings. If it is programmed to ring after 4 or
more rings this may cause excessive delays in fax handling as some models of fax time out after
30 seconds.
Default
No extensions are set up to receive faxes.
Only 1 extension can be assigned to receive fax calls.
