A:Answer I find it easier and faster to just yell! To use the intercom, first go to MENU, then to SETTINGS, then to HANDSET NAME, and assign unique names to each extension phone so that it is easier to distinguish one extension from another. This must be done from each extension once, otherwise it is necessary to remember the number of each individual phone. After doing this to each phone, the Intercom feature can be used by again going to MENU, then to INTERCOM, THEN select the desired extension or ALL phone's.
