Did you test this ?
My experience is the 'reinvite' does not work in the setup
you descripted. I always have to set 'canreinvite=no' in
asterisk config or the audio will not come through.
If you have only one phone on both NAT's and you can do
port-forwording on both firewalls, it can work, but that
scenario is highly uncommon.
The audio stream is setup on some random port, so your
firewall will block this by default.

We need more info before we can tell you the answer.
