Advantages: This option does not require a second physical line for faxes.
More incoming telephone lines can be added as you grow. You can keep the
same fax arrangement.
Disadvantages: Your phone company may charge a fee for the distinctive
ring. If you choose this option, you will require the distinctive ring service
from your telephone company.
Option 3 — Automatic fax detection via the auto attendant
The auto attendant can detect incoming fax calls and route them
accordingly. To enable this, an auto attendant must answer all incoming
calls with your pre-recorded message. It will listen for a fax tone to
determine if the call is an incoming fax. If so, the call is routed to the fax
machine, otherwise the call follows your Call Handling settings. You must
create an auto attendant to use this method.
Figure 23: Automatic fax detection via auto attendant
Advantages: Calls are automatically handled for you. No distinctive ring
service and no listening to ring patterns is required. Incoming telephone
lines are shared between all phones and faxes, making better use of your
resources.
Disadvantages: Some older fax machines do not emit a fax (CNG) tone.
Therefore, the auto attendant cannot detect incoming faxes from those
devices.
Options 2 and 3 require settings to be programmed into the unit using the
configuration software. For more information, see 2.2.6 Fax information on
page 51 and 2.4.2.4 Automatic fax detection on page 89.
If your auto attendant volume is set too high or if your incoming
telephone lines are noisy, the auto attendant may have difficulty
detecting the incoming fax tone and therefore not route the call to the
fax machine. You can solve this problem by adjusting the volume. For
more information, see 2.6.2 Audio Controls on page 111.
