Converting PCAP to WAV How would I go about converting a RTP stream from a pcap file to wav format with a command-line tool such as sox?

Here you go!
1\. Enter `RTP` in the display filter in Wireshark when the capture is open.
2\. Now select an RTP packet in any stream and click on the menu option `Telephony`.
3\. Go to `RTP`>`Stream Analysis` and click on `Save Payload` button.
4\. Change the format to `.au` and choose a name (lets say `test.au`) and location for your file.
5\. Play it using your favorite audio player.
OR
5\. Run the following command to convert the `.au` file to `.wav` if you like `.wav` files better: `sox test.au -V -t wav -b 16 -c 2 test.wav`

Hope that helps!
