You can configure an Ext key as the line key. You can press this key to enter the pre-dialing
screen when the phone is idle. You can also press this key to place a new call during an active
call, and then the original call is placed on hold. For more information on using the line key, refer
to Using the Line Key on page 44.
To configure an Ext key as the line key:
1. Click on Dsskey->Ext Key.
2. In the desired Ext key field, select Line from the pull-down list of Type.
Quick access features like intercom and voice mail should be configured on your SIP server in
advance to make sure they will work on your phone. Contact your system administrator for more
information.
If more than one expansion module is connected, select the desired expansion module from the
pull-down list of Expansion Key.
Feature codes may vary between different servers.
