A system and method of using two-way paging to establish communications with a mobile party having a Personal Telephone Number. The mobile party is equi pped with a two- way pager which the party may use to provide call control. The pager is per iodically queried by a network and/or paging service to determine whether or not the pager is reachable. If the pager becomes unreachable, and thereafter a call is placed to the party's Pe rsonal Telephone Number, the network routes the call to a default station. If the pager is r eachable, any one of a number of alternative call routing procedures may be invoked including: re gistration type routing, call-by-call routing, revertive calling, call examination routing, and subsequent routing. In one possible embodiment, a Customer Routing Point is used to store the pa ger status along with other call routing information, and a Network Control Point is used to carry out the appropriate routing procedure. Other possible embodiments include: using an adjunct to perform the functions of the Customer Routing Point and Network Control Point; and c ombining an adjunct with a Customer Routing Point and Network Control Point.
