Abstract	Bandwidth utilization is one of the main problems faced when transferring the voice traffic from PSTN to Internet. Due to the application of point-to-point technique in serving the VoIP calls over Internet, the ratio between the payload and its related header is very small for the applied protocol (TCP/IP). The Internet has been calibrated to use relatively large packets. If a substantial amount of Internet traffic becomes voice traffic, it will require a concomitant increase in Internet capacity, because the smaller voice packets will consume significantly more of the overall bandwidth. For optimum consuming of the Internet bandwidth without increasing in Internet capacity, an efficient mechanism is proposed for controlling the transmitted bitrate of voice packet according to the status of the Internet. It uses the buffering technique for reducing the transmitted bitrate. It ensures an accepted end-to-end delay, and increases the bandwidth utilization of the current voice packet.
