Implementation itself shouldn’t be to difficult. Especially because at that time I just finished the Wireshark plugin (Ethereal at that time) doing the opposite, extracting and reproducing the voice information from RTP stream captured, the knowledge gained there would make all the development at packETH much easier. There were already some tools available for this purpose but adding this feature to packETH wouldn’t be to hard.

Since packETH is sort of packet generator I came to the idea, to send the RTP packets that actually carry some real voice inside. Sometimes there was no voice at all coming out of VoIP phones, sometimes the quality was bad. This post should be written some 10(?) years ago when I really needed this feature at my work, but since from time to time people ask about this and how to use it with packETH, here are some instructions.Īt my former job working for verification department there was always some argument with the developers of VoIP hardware regarding the voice quality.
