Abstract

A method and system for transmitting a call in a client/server architecture. A client device initiates a telephone call and converts first analog voice signals associated with the telephone call to digital signals. The digital signals are then transmitted over the Internet to a first gateway server. The first gateway server processes the digital signals using a codec algorithm and transmits the processed digital signals over the Internet to a second gateway server. The second gateway server converts the processed digital signals to second analog voice signals and transmits the second analog voice signals over a public switched telephone network.
