First Claim
1. A non-transitory computer readable medium storing computer readable instructions executable by a processor of a call bridging server for implementing a method comprising:
- receiving a request from a first mobile station at the call bridging server, the request for initiating a voice call to a second mobile station, wherein the request is formed using one of Short Message Service (SMS), Unstructured Supplementary Service Data (USSD), a web browser, and a voice-based call;
initiating a first call leg from the bridging server to the first mobile station;

Abstract
Disclosed is an enhanced system and method for bridging calls across telecommunications networks, including an illustrative application of the invention as it relates to international roaming among prepaid wireless subscribers. For instance, whenever wireless subscribers roam internationally they may invoke the system by keying in an Unstructured Supplementary Service Data (USSD) short code followed by the number to be dialed. Said subscriber'"'"'s prepaid account is then decremented in real-time (until such account is fully depleted). A key feature of the disclosure generally is the bridging of the call legs between the wireless subscriber initiating the telephone communication and that of the receiving party through a series of general purpose databases and computers without requiring modifications to existing core network or handset infrastructure.
