Sort of.  Some IAX encryption code went into CVS a while back, but it 
was more of a "talking point" than anything else, meant to give 
interested developers a starting point.  The -dev and -security list 
archives have some discussion about this.  I don't think there's been 
too much continued work on it, but volunteers are always accepted!

For SIP, native encryption should be done through SRTP, which many 
people have asked for but nobody has really delivered.  Again, you will 
find some good background discussion in the list archives.

Running IAX over stunnel would probably be feasible if both sides of a 
tunnel were machines. That's at least a little closer to to native, and 
very easy to set up.  However, I don't think that's what you were 
looking for... :)
