Using a Paging Group as an Intercom
While not a true Intercom feature, a member of a paging group can answer a page as a two-way interactive call by using the dial code *80.
While this can be used by any member of a paging group, once the dial code is used, the page is converted into a two-way phone call between the originating pager and dial code user.
Example:
Phone A dials Paging Group extension 610.
Phone B, C, D, E, receives a page.
Phone C dials *80 while on the page.
Phone A & C are connected in a two-way conversation; Phone B, D, E are disconnected from the page.
