A button set to this function allows the user to drop a call from a conference.

If an extension already has a button set to this function, creating another button with this function will automatically clear the setting from the existing button.

On 1400 Series phones a list of conference parties is displayed from which the user can select which call to drop.

On ETR phones, the last added external party is dropped.

To access this function without a programmable button:

On DS and ETR phones, press FEATURE and dial 06.

On BST phones, press FEATURE and dial 934.
