[Users] SIP trunking requirements

I'm working on a project involving a SIP trunking provider that  
requires a b2bua with registration.

I noticed on the home page that openser is not a b2bua. Is there an  
architectural limitation of openser that prevents it from being a b2bua?

A common setup for the b2bua will be NAT traversal. Currently, we are  
using an Ingate SIParator 19 appliance but we would rather use pure  
software. I haven't been able to find an open source b2bua that can  
bind to multiple addresses for NAT traversal and register with the  
SIP trunk provider. Asterisk is pretty heavyweight for the basic SIP  
mangling I want to do. Any suggestions?
