Will this help with reinvites with asterisk behind nat?

I've tried this with 1.2.9.1 and had problems where the ITSP sees the 
internal address of the NATed asterisk box.  Here is the network config:

Polycom 301 ->
Internal-A (192.168.x.x) ->
Asterisk-A/NAT ->
(Public Internet) ->
NAT ->
Internal-B (10.x.x.x) ->
Asterisk-B ->
NAT ->
(Public Internet) ->
SIP ITSP (Teliax)

I have tried various combinations of nat and canreinvite settings in 
sip.conf but I'm still getting only reinvite functionality.

If I use IAX2 between asterisk-a and asterisk-b there aren't any 
problems of course. I need to do some testing taking the ITSP out of the 
equation, but I'm concerned that the ITSP is seeing the internal IP 
address from Internal-B.
