Answering Machines
You can use an answering machine to answer calls at night when you are not
there, or during business hours when you cannot get to the phone. An
answering machine can share an extension with a phone (via a bridging
adapter) to answer calls to the extension. Figure 7-3 shows an answering
machine set up for personal use at an extension.
If you own an AT&T answering machine with the Call Intercept feature, you can
pick up a call that has been answered by the answering machine by joining the
call from any MLS- or MLC-model phone. When you do so, the equipment
controller sends the answering machine a signal that causes it to hang up.
To Program:
1. The answering machine will answer any call that rings
(the number of times a call rings at the answering
ANS machine’s extension before the machine answers is set
MACH at the answering machine itself).

Bridging all calls, set Line Ringing to “immediate ring.” If the
Adapter answering machine is a backup, set Line Ringing to
“delayed ring.”
3. If you set Line Ringing for delayed ring and the line
assigned to extension jack X is also assigned to other
extensions as a secondary line, adjust the answering
machine to answer on the sixth or seventh ring so that it
does not answer calls before someone else can.
