In short, yes. Every single call on Polynom is end-to-end encrypted. This is facilitated by the server. But what if the server is compromised? The answer is simple. Use Social Encryption as another layer of security, and even the server will have no knowledge of the call's content. With Social Encryption in your VoIP call, you have a user owned and controled layer of end-to-end encryption wrapped inside the server controlled end-to-end encryption. The call is still crystal clear. Our cryptography is future proof, DPI resistant, and quantum proof.
VBR makes VoIP calls more efficient, because your client will broadcast smaller packets when you are making quieter sounds in a call. This is the default setting. If you have reason to believe that your encrypted calls are likely to be sniffed, turn VBR off in your client and it will always transmit the same size VoIP packets, making it impossible to sniff when you're speaking out loud or just breathing on the call.
