The tool can work in multiple ways. If you have it just receive RTP on a
socket, or analyse a packet dump, then I expect it to work fine. I'm not
sure however whether running pcap in promiscous mode would be possible.
I'm just guessing here, I don't know Cygwin much.

Copying Olav Kvittem who wrote the tool,
