determining whether a service node serving said call has voice dialing data for a calling station of said call;
if said service node has said voice dialing data, completing said call using said voice dialing data;
if said service node does not have said voice dialing data, broadcasting a request for said voice dialing data to other service nodes of a telecommunications network;
if another service node has a voice dialing data file for said calling station, responding to said broadcast request by transmitting said voice dialing data over a wideband wide area network to said serving service node; and
using the transmitted voice dialing data file to identify a telephone number corresponding to a word or phrase spoken by said caller completing said call.

Abstract
An arrangement for providing voice dialing service to wireless subscribers when they are not being served by their home mobile switch, and service node. When a voice dialing request from a roamer is detected, the voice dialing data file of the roamer is requested by a broadcast message from the home service node of the roamer. The home service node responds to the broadcast request by transmitting the voice dialing data file to the requesting service node. The requesting service node retains the voice dialing data file as long as there are sufficiently frequent requests (e.g., once per day), for voice dialing service from the roamer. Advantageously, this arrangement allows voice dialing service to be provided to roamers as well as to mobile stations in their home area.
