Just some thoughts based on my experience...
After months trying to make everything work using rtpproxy-mediaproxy with
almost everything accomplished but video, I tried to switch to stun solution.
All my problems are gone now, I have audio, video, presence and instant
messages working like a charm. And most important media server doesn't flow
thru my server so network load remains very low. I have been testing for some
days now and I'm quite happy since I still have to stumble on major problems.
Now some considerations... On a poll onsip.org STUN usage is very low and
rtpproxy-mediaproxy rule as NAT trasversal solution. Why don't people use
stun? Has it some major drawbacks I still haven't found? What are main
advantages of rtpproxy-mediaproxy solutions?
I'm really curious to know serusers opinions about this issue.
thank you all for your two cents ;)

STUN does not work if your NAT is Symmetric. For example all Linux NATs
or routers with Linux OS like the Linksys ones. Unless you have full
control on what type of NAT your customer will deploy, it will be very
hard to stick to an all STUN solution.

Hi Lucas.
May I ask you which STUN server are you using?

I have many linuxes around there, and many linksys routers too, and had no
problems with STUN at all. In fact, when I run my stun-client application
behind a linux-like OS, this is what I'm told:
Port restricted NAT detected - VoIP will work with STUN Preserves port
number Does not supports hairpin of media
