Abstract
Abstract A mobile paging telephone call back device determines and adds the appropriate prefix to a received call back number. The call back device includes a pager, a control unit, an automatic dialer, and a cellular telephone. The pager receives a page message from a paging system central controller. The control unit extracts a dialable telephone number from the page message, determines the appropriate prefix to be added to the telephone number, and adds the prefix to the telephone number. Using the telephone number with the added prefix, the automatic dialer completes a call back for the cellular telephone.
