Hmm - please ignore the last paragraph - while I can now successfully
run "sipp" with pcap support with the above commands, RTP streaming is
NOT working. I mistakenly connected to something else than SIPP,
leading me to think that RTP streaming was working :)
I've changed the "pause" instruction in my scenario to match the
approximate length of the pcap file. It seems that the incoming PRACK
message sent by the client I'm using is coming in at an unexpected
moment (during the pause), causing the problem I'm now getting.
Here's SIPp output:
