I think the root cause is something different.    I think the problem is the

I tried that (only needed to add rewrite_contact=yes) but it didn't help.

BTW, the CONTACT: line holds the correct ip!  Only the FROM: line holds the
wrong (private) IP.

I'm still learning SIP...but I assume the FROM should also hold the
rewritten public IP.  Just don't know how to force Asterisk to do that.
