RELEASE |
Release lets users disconnect from a call without having to hang up the handset. Hanging up a call this way means they will not get the reminder tone in the handset that the phone is off-hook. It also allows incoming calls to ring through to the telephone.
This feature is mainly used when a headset is connected to the telephone through the handset jack. This allows users to leave the handset off the cradle while calls are made and answered using the other buttons on the phone.
Calls arriving at the telephone will ring and when the line is selected, the call is connected through the headset.
