That's great news!  I had a sinking feeling when I heard the words
"authenticated invite".  

Unfortunately some large voip companies (cough cisco) are locking down
their sip servers to only talk to established peers.  Perhaps I'm
missing something crucial, but these companies still have DID numbers
for their employees, so locking down the sip server just forces the
call to go out via the PSTN.

So are BV customers listed in the in e164.org dns zone (or some other
publicly accessible routing database)?  I would love to have some way
to bypass the telco when calling friends without having to put a
by-hand entry into asterisk for each person that can accept direct
calls via some voip proxy.
