A unified digital dispatching system that can be deployed on a server for internet communication applications.

Abstract

The invention relates to a unified numbering system on a server for an internet communication application on a user's mobile device. The system includes a roaming checker that receives origin information from the server, in response to the user identification of the mobile device running the application. It also receives location information of the mobile device and determines whether the user is in the origin or another area. The application router receives the unified number dialed by the user, the origin area and, if the user is roaming, another area. The application router provides the first transaction and its address is associated with the unified number in the origin area and, if the user is roaming, the second transaction and its address is associated with the unified number in another area, for the user to choose.
