Abstract
A method and system for transmitting a call over a packet switched network. A gateway server receives a telephone call and converts analog voice signals associated with the telephone call to a stream of digital data. A first part of the digital data is processed using a first codec algorithm and transmitted over the packet switched network. A change in network conditions is detected. A second part of the digital data is processed using a second codec algorithm and transmitted over the packet switched network.
