The RTP doesn't need any rewrite in NAT scenario vs. no-NAT scenario. 
SIP does, but it's unlikely to affect simultaneous calls count considerably.

The test itself is not complete, though, as the performance is likely to 
depend heavily on the RTP PPS (packets per second) rate, which could 
range from 100 to 33 depending on the frame size in use. I also could 
not find the frame size in the report, though it's possible that I have 
overlooked it.
