Hi, I have used latest sipp on LINUX as a valuable tool for generating bulk calls.Thanks for the great tool and the hardwork put by unselfish hardworking engineers.Our company makes SIP based voice gateways and important way to ensure it's quality is to make bulk calls and assess the quality metrics (like MOS,PESQ,PSQM,hit and clips etc). We use the commercial tools from Spirent and Empirix to do that. But as the features in our gateway grow , it's not economically feasible to buy multiple licenses of these expensive equipments so the need for Sipp as an alternative viable solution.I have started implemeting sipp to add to our automation process; These are some of my road blocks. 1. sending the different media files like G711(A/U), G723.1,G.729 etc and DTMF tones and playing it back using RTP echo option. Done.But I am not able to introduce real time network scenarios like Jitter,packet loss rate etc in general add all the RTCP parameters. Is there a source code for it ?Also I am not able to stop the test on any type of unexpected error. 2.Has anyone done any voice quality measurement (not just listening) on the received packets? 3.Is there a limit on max calls made/received from client/server when playing pcap files? 4.Has anybody tested STUN,TURN and ICE NAT traversal features with SIPp as a test tool? 5.I was thinking of evaluating WinSIP(from touch stone) as another alternative; but no commitment from our management. Has anyone used that and opinions on that?
Thanks very much, Kad _________________________________________________________________ All-in-one security and maintenance for your PC.
