Hello Daniel

Actually SIP signalling goes perfect, and i can see in RTP asterisk log that RTP packets are being sent, so I suppose there is something stuck somewhere in RTP maybe related with RTP Engine

I updated to latest version through git but still stuck there. Now I can see that the config file (ngcp-rtpengine in etc default) has changed so I'm not sure how should this impact (not ADDRESS neither ADV ADDRESS now I see an Interfaces parameter)

I also find for some reason very possible that somehow rtp traffic is not getting through. ICE candidates are being negotiated, so I feel that the route is clear, so maybe there might be some crypto issues as you point out, but update has not been enough :(

Any other ideas?
