I just tried this, I set the bindaddr=outside NAT address and my sip registration messages now have the correct ip address in the VIA field!!!!!!
I tried the fromdomain=outside NAT address , but it didn't change anything in the sip message. And setting the bindaddr=outside NAT address didn't break the SIP thread. As the registration messages work fine.
