Hello to everybody,
Are there enough voip server in Europe to support brand new video-voip??


sometimes l heard my friends: please don't use again your nerd app, do like all "normal" people..... voip calls works so perfect!!!!!!

As I understand the new video/call system, it reliest on WebRTC[1]. This
system only uses a centralized server to put the caller and callee in
relation. After that, the whole video-call or simple phone-call is
handled peer-to-peer.

This means the infrastructure currently in place is more than sufficient
and with WebRTC, it is even probably less costly than the old one (or
did Redphone already did p2p?)

How can peer-to-peer work behind NAT-routers and/or shared IPv4 addresses?

I know there are workarounds like UPNP Port Forwarding or UDP Hole
Punching, but i doubt they are reliable/available enough to be used in
signal.

Signal uses WebRTC, which uses STUN, resorting to TURN (= relay
everything) only if STUN doesn't work, for example in the case of
symmetric NATs. The technology is not new and quite proven.

How common are non-symmetric NATs? It sounds to me like every webrtc
call with me (be it home wifi, eduroam or mobile data) will have to fall
back to TURN, so the server capability question appears valid to me.
