A button set to this function allows the user to enter an account code prior to making a call or during a call.

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

This function is only supported on a button that includes LED/LCD indicator. The indicator is lit when the function is enabled.

Once a user has associated an account code with a call, only that user can change the account code by entering another one.

To access this function without a programmable button:

On DS and ETR phones, press FEATURE and then dial 12.

On BST phones, press FEATURE and dial 900.
