This question is related to live captures of rtp via sniffers like ethereal, tcpdump o rtpdump.
There are tools like tcpdump, or rtpdump which capture rtp streams of conversations produced over the internet with packet sniffer.
I have the idea of capturing this rtp strings from the sniffer passing them to LabView and make automated analysis of that rtp searching for audio quality as MOS and R Factor Measurement on voip networks, I know Labview can do it and:
1) The captures are made from the already in place network card on the pc
2) The RTP is placed on log files on the flight which are prefiltered with the rtp information just need to apply or select the codec that PCM or G729 of the call in progress to decode the RTP and handle it as an audio signal like the one capable of capture from the audio card of the PC.
If you can give me some guidelines on some driver available at LabView for RTP processing it could be a great tool for the VOIP industry.
Kind regards,
Saul Bejarano
