It means that the router has been rewriting the SIP packet !!!
It has replaced the public IP address by your personal IP address. It is
a bug in the router.

I suggest you to try the following :
- do not use STUN at all.

I do not think you are in a real NAT, 23.X.X.X does not sound like a
private address too me.
