Intercom
You can configure an Ext key as the intercom key. This is especially helpful in an office
environment as you can connect to the operator or the secretary more quickly by pressing the
intercom key.
To configure an Ext key as the intercom key:
1. Click on Dsskey->Ext Key.
2. In the desired Ext key field, select Intercom from the pull-down list of Type.
3. Enter the remote extension number in the Value field (e.g., 1006).
4. Enter the desired value in the Label field or leave it blank.
If you leave this field blank, the LCD screen of the EXP40 expansion module will display the
default label “Intercom”.
