Abstract
This article presents an experimental study that extends the current knowledge of the VAD/DTX codec influence in the transmission rate. It considers the new GSM AMR codec as well as G.723.1 and G.729B. The type of the encoded frames have been studied in order to determine the real bit rate and the SID frames effect. The influence of the number of frames per packet have also been addressed, showing that there are optimal values that minimize packet bandwidth consumption.
The work leading to this article has been partly supported by CICYT and the EU under contract number 1FD97-1003-C03-03.
