Telephone Service for New Zealand
FaxAbility
FaxAbility is a service offered by Telecom that allows you to have an
additional number on one phone line, with its own distinctive ring
pattern. This way, when you get an incoming call, you can identify the
number being called by its ring.
How Will the Fax Machine Treat All Other Numbers?
FaxAbility mode ensures that the machine will answer calls to the
FaxAbility (secondary) number. When a call comes in to your main
number, all the phones will ring. You can set an external answering
device (TAD) to answer calls on the other number(s). (See the chart
in the following page.)
What is the Advantage of Using the FaxAbility Function?
Using FaxAbility is the most efficient way to receive both fax and
telephone calls on the same line. It is much easier for your callers
who dial manually. The fax machine will answer with receiving tones
so they will not have to press an activation code. And the people who
call to talk on your main number will not have to talk to your fax
machine. Basically, it gives you two independent numbers without
the higher cost of a second line.
