Norstar-PLUS Modular ICS 2.0 System Coordinator Guide

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.

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.

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.
