Personalizing Your Telephone
Activating Door Relay
If the Activate Door Relay feature is enabled, you can unlock a door (i.e., “buzz” it open)
through your telephone.
You can enter the Activate Door Relay feature code while idle or while on a call. This allows you
to activate the feature while talking to a communications device mounted at the door without
first having to hang up. When activated while on a call, the feature will not affect the call in
progress other than to show a short confirmation on the display.
You can add the Activate Door Relay feature to a phone keymap button, just like any other
station feature.
To unlock a door:
While idle or while on a call, dial 332. The door is unlocked.
