Yes, that is, I comment it to you because you said:

"Unfortunately [...] $si contains the reported remote IP address, not the public IP address that the message has been received from."

I think you are trying to get something impossible: the last router IP through which the packet arrieved to your OpenSer. That's not possible, note that layer 3 (IP) doesn't notify the intermediary IP address in the received message, you just can see the source and destination.

No, I'm trying to get to the public IP address of a NATted SIP UA. This address is not found in the SIP message, but OpenSER knows it otherwise it couldn't reply to it ;-)

You could try to parse the Via headers to find the correct IP.
