With the Whisper Paging feature, the page is unique because only the person on the paged extension can hear the page. Other parties on the call cannot hear the page, and the person who makes the page cannot hear anyone on the call. If the paged user has a display telephone, the paged user can see who makes the whisper page.

For example, users A and B are on a call. User C has an urgent message for user A and makes a whisper page. All three users hear the tone that signals the page, but only user A hears the page itself. User who make the page cannot hear users A or B.
