Having a STUN client embedded in Asterisk makes a lot of sense.

I've been trying to find anything we can use with a good license, or  
just a
good Linux command-line client. Could not compile most of them on my  
systems...

Anyone with any ideas?

If there's no compatible libraries, we could possibly provide hooks  
for external programs.
