Daniel, thank you for your answer. You did not understand me completely. This is my fault.
Let me put it this way. I want kamailio to handle NAT (fixing nat only from client's side) not being registrar itself. This also includes nat pinning. usrloc module is a dependency for nat pinning in nathelper module. Request: UAC behind NAT ===> kamailio == fixed contact ==> freeswitch Respnse: freeswitch == 200 OK ==> kamailio (store contact in usrloc, start pinning) == 200 OK ==> UAC behind NAT Kamailio starts pinning UACs behind NAT only after successful authentication and registration on freeswitch box. No nat fixes between kamailio and freeswitch (only from UAC). 2017-01-03 14:33 GMT+02:00 Daniel Tryba <d.tr...@pocos.nl>: > On Tue, Jan 03, 2017 at 12:58:20PM +0200, Vladyslav Zakhozhai wrote: > > The main question here is about nat pinning.
