The head end is the one thing Internode don't seem to have yet released in their rollout...  This leads me to believe that perhaps SIP is one of the more tricky things to get to work (which is ironic given it is probably one of the things that most hates IPv4 NAT).

Might have changed since I left, but at the time it was because SIP to an ACME Packet
SBC works fine through lots of layers of NATv4, and Broadworks was dragging their 
feet as a vendor (I think they've rectified now) so there wasn't a huge impetus to move
on it.

Remember that Internode controls the entire path between the customer's CPE and the
SBC, and can (does) take responsibility for it continuing to work.  Makes it a bit
different from most other applications, where either the server or the client is in
someone else's ASN.
