Does anyone have any reliable data on rtpproxy dimensioning, i.e. just about how many calls per box (and what kind of specs) it can really handle in actually-existing practice, not in theory?
The one time I used it for NAT traversal was on a pretty beefy quad-CPU box, and I started seeing clicks and distortions in the calls beyond a load of 90 or so. However, I was never able to decisively ascertain that the cause is not the network.
