You could try running the following command from the OpenSIPS server: curl -s checkip.dyndns.org | sed -e 's/.*Current IP Address: //' -e 's/<.*$//'
See if its going out with the proper address. More than likely the NAT statement on the router is not setup properly for Reverse NAT Policy.

You said that ALG was disabled in the router, but either that is incorrect or there is some other piece of equipment changing the message. This is clear because the contact is not the only header that is changed. The ‘received’ parameter of the Via address was also changed from the public address of the UA to the private address. Only an entity within the private network could know that address, so it is almost certainly the router doing it.
