regarding PJSIP using under nat - stun and a=media port in SDP
<p>stun server was return IP:port pair:</p>

<p>2013-01-11 15:15:55.849[14416:7f0b] ========> 15:15:55.849    stunresolve !.STUN mapped address found/changed: 22.22.22.22:50282</p>

<p>but INVITE SDP don't modified correct port in m=audio, just IP in c=IN record.
How it can solved?</p>
