Abstract: A unified number coordinator is in a server for an internet communications app on a mobile device of a user. The coordinator includes a roaming checker which receives region of origin information from the server, in response to identification of the user of a mobile device running the app. It also receives location information of the mobile device and determines if the user is in the region of origin or in a different region. An app router receives a unified number dialed by the user, the region of origin and, if the user is roaming, the different region. The app router provides a first business and its address associated with the unified number in the region of origin and, if the user is roaming, a second business and its address associated with the unified number in the different region, for the user to select.
