Answering calls
Answering an incoming call
There are three indications of an incoming call: ringing, a line button
flashing, and a message on the display. You will not necessarily
receive all three indications for any particular call. For example, you
may have a line that has been set up not to ring at your telephone.
If so, you will see only a flashing line button. There are many
possible combinations, depending on how your system is set up.
See “Choosing a line using a line button” on page 48 for more
information on the use of lines.
If you receive a priority call and your telephone has no free internal
line buttons, you cannot transfer the priority call, you must accept or
release it.
Line buttons
One line button for each line is assigned to your telephone. Press
the line button to select the line you want to answer or use to make
a call. Having several line buttons allows you immediate access to
more than one line.
The M7100 telephone has two intercom paths which are used
instead of line buttons to answer and make calls. Each M7100 can
be assigned two lines. You can press
˙ to switch between
two calls, one active and one on hold.
Incoming line group buttons
You have one incoming line group button for each incoming line
group assigned to your telephone. You use an incoming line group
button just like a line button to answer calls, but you cannot use it to
make a call.
M7100 telephones do not have incoming line group buttons.
