A telephone signaling system is operative outside of the traditional calling and data transmission paths to provide originating to termination signaling. Routing of the signaling is in response to a locator system which includes a data base of terminations and a system for keeping up to date information of current termination locations of the intended recipient. In one illustrative embodiment the termination equipment includes locator devices such as GPS locating devices. The information supplied by the GPS locating device is provided to a central data base which routes the signaling system to the intended recipient termination device. The central routing system then selects a voice and data transmission path that optimizes some preselected criteria of transmission. A typical criteria could be cost, or bandwidth or some combination of criteria to be optimized.
