  • Method of delivering paging messages using voice mail
    Patent number: 5418835
    Abstract: In a cellular communication system, the delivery of a page or message is attempted over the system to a user of the system. If the page or message is undeliverable before a set period of time, the page or message is converted to a voice mail message. The voice mail message is then stored in the cellular communication system. When the cellular communication system is accessed by the user, the user is notified of the existence of voice mail by either a text page or an automated voice radiotelephone call. The stored voice mail message is then delivered either automatically, or at the user's request.
