ethereal can save the payload but I don't believe it can be done from the command line. > and then to find a nice simple scriptable tool to compare the audio quality. I'm pretty sure this tool does not exist, at least not in the open source world. I looked for something like this a few years back and the only things available were commercial packages for very high prices. Let me know if you find anything. > <!-- Play a pre-recorded PCAP file (RTP stream) --> > <nop> > <action> > <exec play_pcap_audio="pcap/g711a.pcap"/> > <exec command="tcpdump-vent 9 -s 0 -w uac_echo_[remote_ip]_6000_`date > +%F_%T`.pcap src host [remote_ip] and dst port 6000"/> > </action> > </nop> I'm confused; why are you playing back and capturing the file in the same script? I assume this is just proof of concept? In any case I do see the application of your idea and it looks very promising. I only used SIPp for the first time yesterday and already it has helped me track down a very elusive problem (can you believe we had a client with one PRI channel that was bad!? I didn't even think that was possible. I never would have found that without an automated testing tool like SIPp).
