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 gives 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.
