Using Telstra^® FaxStream^® Duet^® is the most efficient way to receive both fax and telephone calls on the same line. When the voice call comes in, all telephones (extension and external) and the fax machine will ring to alert you to pick it up. If a fax call comes in, the fax machine will answer automatically without ringing, whereas the extension and external telephones will ring twice with a distinctive ring pattern. It is also a more efficient way of operating a Fax machine with an extension telephone as you do not have to use the remote activation codes. It gives you two independent numbers without the higher cost of a second line.

Incoming calls to the voice number, will have the standard ring pattern of long, long tone, followed by a pause, repeated, while the new fax number will have a different ring pattern of three short bursts of ring, repeated at regular intervals.

When FaxStream^® Duet^® is On and you receive a voice call all extension and external telephones will ring with a standard ring pattern. The fax machine will ring on the third ring with a standard ring pattern. All external and the extension telephones will continue to ring, until you or a telephone answering device can answer the voice number.

When FaxStream^® Duet^® is On and you receive a fax call on the Duet^® number the Fax machine will answer and automatically receive the fax message without ringing. On the other hand, all extension and external telephones will ring twice with a distinctive ring pattern. Do not answer the telephone as you are receiving a fax message.

After you have set the Distinctive Ring feature to ON, the receive mode is set to Manual automatically. Your Distinctive Ring Number does not allow Voice Calls - only Faxes.
You cannot change the receive mode from Manual mode while the Distinctive Ring is set to on.
