VoIP Protocols’ Bandwidth Based-Mini/RTP Header Using Different Codecs: A Comparison

Abstract:
Over the last few years, many multimedia conferencing and Voice over Internet Protocol (VoIP) applications have been developed due to the use of signaling protocols in providing video, audio and text chatting services between at least two participants. This study compares between the bandwidth of the widely common signaling protocol; Inter-Asterisk eXchange Protocol (IAX) based-mini header and other VoIP protocols based-RTP header during the media session using different codecs types. A full duplex bandwidth has been calculated in case of first call, additional call and 30 calls using four common speech codecs. As IAX protocol has a multiplexing feature, so for each additional call, the headers of data link, network and transport protocol are reused. This means that bandwidth value in the first call differs from the value of the additional call. Unlike the other VoIP protocols, both the first and the additional call values are equal since all the headers in the audio packet should be calculated again for each call. The trunking property leads to a performance improvement of IAX protocol over the other VoIP protocols in terms of bandwidth consumption.
