I know, you whant to have a "Man In The Middle" proxy, hidding to your 
customers what are the real "gateways", that you don't own. That's ok .. when 
I say "your own gateways", I mean ... "your own B2BUA's/PSTN Gateways" ..., 
it's obvious that I prefer to proxy also the RTP throught "our gateways", so 
we can have full control over RTP and no fraudulent use of our proxies are 
allowed (if we did not something wrong ...)

I don't like doing accounting on the proxy at all, I prefer to do it in the 
B2BUA/Gateways machines, realtime or quasi-realtime accounting, but not on 
the proxy.
