Use this procedure to allow users to make an announcement over a group of digital speakerphones. By dialing a single extension that identifies a group, users can page over all the speakerphones in that group. Speakerphone paging is one-way communication: group members hear the person placing the page but cannot respond directly.
See Group Paging in Avaya Aura® Communication Manager Feature Description and Implementation for detailed information on paging over speakerphones.
