I'm doing this kind of test but I think the rtp_echo is too limited..... it
seems to work with only one port defined by the -mp option....
This behavior seems not suitable for a load test....
Because of this, I use the play_pcap_audio on the server side too. Works
fine! I could achieve some heavy load on the server with a load of G711
calls.
