Choosing a line using a line button
You have one line button for each line 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.
Line pools
A line pool is a group of external lines that can be shared by
many telephones. You can use a line in a line pool to make an
external call.
You have entered the number of a telephone
that is not in service.
The telephone you have called is on another
call. Press
LATER to use the Ring Again or
Message features.
The call you are trying to make has been
restricted in programming. A possible reason
is time-of-day restrictions on certain calls.
Press YES to use Ring Again. Press NO to
send a message. See “Sending messages”
on page 98 and “Turning on Ring Again” on
page 61.
