Flexible realization scheme for streaming voice signals over IP networks

Streaming of voice over Internet protocol (SVoIP) means transmission of real time voice signals and associated call control information over an IP-based network. This paper introduces a microcontroller based system that can be used for making a SVoIP gateway (SVoIP GW) that uses TCP/IP Stack. Using this technique one can transmit the voice of the POTS (plain old telephone service) over the internet by making conversion of the analogue voice into IP-packet. Further an OPNET program is used to simulate a system to accommodate a voice over IP networks .
