ABSTRACT:
A communication system and method for minimizing international roaming costs leverages an existing communication network to convert roaming communication sent to and from a mobile telephone into a series of local telephone calls to and from the communication network. Using a universal address, subscribers of the communication system can initiate or participate in real-time communication through the network while roaming outside of a home system, without incurring roaming charges.
