I need to test the new ser/radius/mediaproxy server we have bought. As a fast upper bound to the maximum number of concurrent calls I tought to use rtpgenerator, but it can't increase the number of simultaneous calls more than 50 ... Is there any way to increase that limit ? (why it is set anyway ?) Launching a second instance raises cpu usage from 0,5 to 98, so it doesn't seems a good solution ...
