Created by: Wes Schochet on 12-05-2010 07:45:07 PM Hi All- I am trying to come up with a basic call recording routine. I am able to capture the packets just fine, but have not been able to convert the stream into anything playable. Up to this point, I have captured the packets, stripped the headers off all of the udp packets and written the results to a file. This has produced barely discernable. I have tried converting the byte stream from G711 to PCM based on some bit shifting and flipping algorithms like this one: http://en.wikipedia.org/wiki/G.711. Also produces very poor results. Can some one point me in the direction of some documentation or an algorithm to do this?
