Yes, I wasn't looking for "far end" (in the service provider) solutions, 
but the "near end" seems appropriate...

Anyway, I was looking for a smaller solution, something for small 
offices, from 2 to 10-20 phones.

Now I was asking myself if an Asterisk solution could work.
Can Asterisk work as a SIP proxy behind a NAT?
Does it have a STUN client?
