When you are running Kamailio behind a NAT you should use advertise parameter of listen address. According to documentation " A typical use case for advertise address is when running SIP server behind a NAT/Firewall, when the local IP address (to be used for bind) is different than the public IP address (to be used for advertising).". For example:
listen=udp:10.10.10.10:5060 advertise 11.11.11.11:5060 For more info refer to http://www.kamailio.org/wiki/cookbooks/3.3.x/core#listen Regards Gholamreza Sabery Tabrizy On Wed, Jan 13, 2016 at 2:39 AM, Daniel-Constantin Mierla <mico...@gmail.com > wrote: > Hello, > > can you get the SIP trace with all the packets of such dialog outside of > the NAT router?
