never compared the two of them. I used only rtpproxy so far and I was 
very happy, mainly regarding the development and community support. 
mediaproxy is in first place python, which slower than native C.

Sometimes I prefer not to mess up with the kernel, I rather have an 
application crashed and restarted by monit or similar tool, than a 
kernel panic and full system crash. I do not know if using just kernel 
space is much faster as I haven't tested, however, there is a C 
alternative in SER (to be available soon via the http://sip-router.org 
project) for rtp relaying via kernel:
http://cvs.berlios.de/cgi-bin/viewvc.cgi/ser/sip_router/modules/iptrtpproxy/

I would bet on it if I would get into rtpproxy limitations, so far 
didn't happened.

RTPProxy has the advantage of a public source repository, which is more 
convenient for me to deal with, as opposite to tarballs downloads. With 
a public repository I can track changes, report and fix issues easier.

To conclude, it might be just a matter of choice for rtp relay, but the 
nathelper module is much flexible and supported by many core developers 
of kamailio and ser.

Cheers,
Daniel
