However this trick is not needed at all to fix just the signalling as the "Contact" URI (so the dialog target uri) was already replaced in the initial INVITE/200, and it cannot change within a dialog.
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?
