Hello!
 
Just curious: I do remove_hf("Contact") right after fix_nated_contact() (for whatever reason).
Then the remove_hf() removes anything but the new SIP URI from the message, leaving e.g.
sip:user@received_ip:port
in front of the headerfield following the Contact. e.g.
 
Before:
Some-Header: bla
Contact: Name <sip:user@privateip:port>
Authorization: bla
 
Then:
Some-Header: bla
sip:user@public_ip:portAuthorization: bla
 
How to remove that Contact: after having it nat_helped and then saved?
