Hello!I have next topology: ISP->Kamailio + Rtpengine->WebRTCSometimes I receive from Browser side SDP like below with private IPs in ICE candidates.
- Please explain why it happens?
- How ICE finds a pair? I think Rtpengine obtains packet from Browser and somehow matches with peer (as it can't reach Browser via private IP)
