Abstract: The invention relates to a voice transmission method for saving bandwidth, which can save bandwidth without voice transmission quality being degraded in private network application environment. Since network quality of private network is good and probability of packet loss, disorder and jitter is small, and in RTP protocol used for transmitting IP voice, the RTP packet header occupies a large amount of bytes, which wastes precious bandwidth resources, the RTP packet header for IP private network is simplified according to the invention. The rule of the simplification is to delete unnecessary parts of the structure of the RTP packet header. For example, the simplified RTP packet header includes only flag bit for mute and bits for voice encoding and decoding type of PT packet and only uses a byte. With the simplified packet header, the bandwidth usage rate of RTP packet header can be lowered from 16% to 1.6%.
