Sorry to hook in here but it seems to me you didn't get the point:
PjSIP (like Dan said) is the implementation of a SIP stack and that's it 
(hence the name!).
You're suggesting a completely new library (as in PjXMPP or something 
like that).
You'll find the problems with NAT in every SIP environment where NAT is 
in use.
It's not like it's Asterisk's or PJ's fault or anything like that.
And I definitely do not concur when you say Asterisk or Freeswitch are 
overloaded and susceptible to DoS attacks
(I know first hand because I work for a company that builds 
communication systems for emergency control centers
at the very heart of which sit Asterisk servers... and they are rock-solid).

As to what development is about:
It's also about delivering something that works reliably.
It is definitely NOT always about "more more more features"
(I happen to know a company which likes to deliver new features with 
every new version they release of their software...
and after several years now they still didn't fix some of the most 
annoying bugs BUT HEY LOOK: We've got this brand new feature....)
Maybe it's just me, but after a couple of years in the business I'm 
taking software development (and all the decisions that must be made 
during the process)
rather serious because I know that seemingly "interesting" or "good" 
choices might turn out to have been very shortsighted later on.

The main scope of Pj is media, SIP and platform independeny (did I 
forget anything?).
They've got enough work with it and I think everyone involved does a 
great job.

Just my 2 cents...

Don't bother to respond. This thread is closed for me.
