Mitel 5220 manual Using the Line Interface Module

USING THE LINE INTERFACE MODULE

The 5220 IP Phone supports the Mitel Line Interface Module. The Line Interface Module allows you to make and receive calls over an analog line (Line Interface Module line) connected to your phone. The Line Interface Module operates in either of the following two modes, as determined by your System Administrator:

zLine Interface Module Mode: your phone allows you to use the Line Interface Module line at any time

zFailover Mode: you can use the Line Interface Module line only when the IP connection has failed

Note: Handsfree and on-hook dialing are not supported on the Line Interface Module line.

For information on emergency number dialing using the Line Interface Module, refer to Emergency Calls.
