Checked the RFC, you are right.
Then, what the OP must be implying is that the PSTN UA is not following
original Contact/dialog target URI bound at start of dialog and is
following new Contact (with RFC1918 address) sent in re-INVITE?
Maybe, however it would be solved with your suggestion (inspect the "Contact"
in the 200 from the natted UA and "fix" the private address.
