Silent ring fax detection system

You can also set your fax machine to receive faxes silently, but ring to alert you to a voice call. To do so, set the ringer volume to OFF and set the reception mode to TEL/FAX. When a voice call comes in, a special ringer on the fax will ring. Note that extension telephones will not ring.

Note: During intial ringing before the fax picks up the call, the fax will be silent but extension telephones will ring.
