Hello Everyone, How is possible add to Contact: received=ip ? Is this should be handled by fix_nated_contact() ? I am using default NATDETECT route, but I see in debug fix_nated_contact() executed, but in SDP Contact: stay Contact: sip:102@private_ip:5065;transport=tcp;audio.

From public side client use TCP inbound to kamailio and on local side to asterisk is use UDP. Kamailio have 2 interfaces one public one private.

Any help thank you.
