Group Paging
A group of users can be created with a purpose of receiving voice announcements through the speaker of a telephone set, but it has to be in the waiting mode.
Numbers starting with 0800, 800, 1-800 are usually toll-free for the caller; the called party, however, has to cover the charges on those calls.
