Ah, yes, good point! It was http://trac.pjsip.org/repos/ticket/866

Basically, in pre-1.4, STUN used to be one single point of failure
thing, if your STUN server is down the library will refuse to be
started. With that ticket, we added support for multiple STUN servers,
and the library checks for STUN server usability before picking one
up. The checking uses STUN facility in PJNATH, which is mostly new
STUN, though I thought it should be backward compatible with old STUN
(at least it worked with Vovida STUN in
http://www.sf.net/projects/stun)

You can use stun.pjsip.org.

Cheers
 Benny
