Do you have difficulties with the Sipura SPA-2000 (or other Sipura 
boxes) and Asterisk?  I've found no problems, even behind NAT, though 
I have only tried behind one or two NAT devices (OpenBSD and Apple 
Airport.)

It's surprising that Sipura doesn't include STUN as an option - their 
list of options is so huge that I always assumed I had just missed 
it, but now that I look closer I suppose you're right.  Do Asterisk 
users even really need STUN?  I've never found it to be required 
after the NAT issues were worked out of Asterisk...

No, no problems with a Sipura and Asterisk. The Sipura is impressive,
so I'm surprised that it doesn't support STUN and NAT in a good way,
so we could enable canreinvite
