Daniel,
I hate to open up an old and tired can of worms, but are there any
recent performance tests
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.
that indicate whether rtpproxy or Mediaproxy
2.0 scales better? Mediaproxy 2.0 uses API calls into the kernel's IP
forwarding subsystem now so I wonder if it can do better than rtpproxy
running in userspace.
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
Like you, I much prefer rtpproxy - it's so much
simpler and more
flexible to deal with.
Just wondering.

Howdy,
I'm trying to remove the media/rtp streams from an asterisk server for natted users
so would like to know if this is possible with kamailio.
yes it is possible. nathelper+rtpproxy is the option I use and prefer
because of flexibility and performances. You can see an example at:
http://www.voip-info.org/wiki/view/Kamailio+1.5.x+and+RTPProxy
Qu's:
What is the best option?
rtpproxy/mediaproxy?
nathelper?
If i use kamailio to achieve this does it mean that i still have to carry the rtp streams
through the kamailio server instead?
through the rtpproxy server, which can be located on same or different
machine than kamailio.
Also will i need to change the logon info for the
clients so they now logon to kamailio then i just point registrar to asterisk?
Can i use kamailio for sip trunks to asterisk and carry rtp and natted clients media
streams rather than register to asterisk?
Yes, you can register to kamailio, see registrar and usrloc modules.
Cheers,
Daniel
