Dial Paging
Makes a paging call to an extension or group specified. If no number is specified, this can be dialed after pressing the button. The target extension or group members must be free and must support hands-free auto-answer in order to hear the page.
On Avaya phones with a CONFERENCE button, a paged user can convert the page call into a normal call by pressing that button.
That's from the Help file in Manager, it's very usefull.
