[Asterisk-Users] sip register and nat

As I understand it, & if I understand you correctly, the register
parameter is for the client side.  The nat=yes parameter is for the
server side, so it has nothing to do with your register statement.  The
sip debug displays "no nat" because sip.broadvoice.com is not "behind"
the nat, it's "in front" of it.
