According to this
(http://transnexus.com/index.php/performance-test-results-for-openser-and-rtpproxy)

"For a server hosting both OpenSER and RTPproxy, each 1 GHz of CPU processing
capacity can manage a maximum of 325 simultaneous calls."

I have 2.4GHz for rtpproxy, but CPU/Mem/network is ok, so the
bottleneck should be somewhere else probably..
