This paper addresses a technique for multiplexing voice streams into an IP packet for efficient VoIP transportation. The principles and distinctive schemes are presented and a comparative performance evaluation of the schemes based on a prototype is provided. In this paper, a scheme using a dynamic packet length threshold is proposed. As a conclusion, we show the scheme is beneficial for shortening packetization delay compared with the scheme in which multiple coded blocks in one voice stream are carried by an IP packet and superior with respect to reducing the header overhead and the number of generated packets.
