Shpinev, Thanks for your response.
-M seems to be an unrecognized switch. I have been using rtpbreak to generate the .raw file. Subsequent to which i use sox to convert the .raw to a .wav file. By importing the the .raw file into Hypersignal software, i found that the .raw file doesnt entirely seem to be composed of speech samples, so there could be a problem at the rtpbreak step. This is the command i used to convert rtpproxy's capture file to .raw format rtpbreak -W -r capturefile.rtp Am i missing something here ?
