Hi, I don't know the max limit of sipp considering concurrent calls with RTP, but it is more than 508 calls. In our test case we were able to simulate 5000 concurrent calls with RTP using sipp. In the XML scenarios, we used the command "play_pcap_audio" in order to play media. For completeness, I'll paste the commands we used:
> # On UAC > sipp -r 60 -rp 1000 -m 5000 <DEST-IP> -i <LOCAL-INTERFACE> -sf > <SCENARIO-FILE> -ap <PASSWORD> -l 5000 -s <DEST-NUMBER> > -watchdog_minor_threshold 1000 -skip_rlimit -mi <MEDIA-IP> > # On UAS > sipp <DEST-IP> -sf <SCENARIO-FILE> -i <LOCAL-INTERFACE> -p <LOCAL-PORT> -m > 5000 -watchdog_minor_threshold 1000 -skip_rlimit -mi <MEDIA-IP> The XML scenario files where simple basic UAC and UAS scenarios with authentication extended to play RTP via "play_pcap_audio".
