Answering system

Setting your system to automatically answer calls

Use this feature to separately set each of the four lines to automatically
answer incoming calls in two different ways.
General mailbox (gen MB only):
The called line rings on every extension for each incoming call. If there is no
answer, the caller is prompted to leave a message in the general mailbox,
which a person at any handset can review. The general mailbox stores
incoming messages, memos, and two-way conversations (see Answering
system operation on page 72-78 for more information.)
Auto attendant (auto att):
The called line for each incoming call flashes on every extension, but does not
ring. Instead, the auto attendant answers. The caller can specify an extension
or leave a general mailbox message. When the auto attendant directs a call to
an extension but it is not answered, the auto attendant prompts the caller to
leave a message for that extension or try another extension.
The auto attendant can answer only one call at a time, so you might want to
have more than one auto attendant in your system so that even when a call
on one line is being answered, a second auto attendant can answer another
ringing line. You can designate up to four auto attendants in your system
(see Auto attendant operation on pages 69-71 for more information.)
No answer:
You can disable automatic answering on any of the telephone lines.

An example of a 2-line answering system setup

If you have two phone lines and two or more extensions and you wish to
use the auto attendant, then configure both lines to use the auto attendant.
Then, if a call comes in while one line is busy, it will still be answered by the
auto attendant.
Line 1: Auto attendant (2 rings)
Line 2: Auto attendant (2 rings)
