Mumble is a free, open-source, cross-platform voice over IP low-latency, high-quality voice communication tool. It has great options and performance like very low latency, denoising of audio, automatic volume control, echo cancelation, connection and speech encryption, compression / quality control within the client and a lot more... It uses a client-server architecture where users who want to talk connect to the same server <ref></ref>, and it uses Celt and Speex as the codecs.

Your nick can be easily registered since the 1.2.0 version. After you made a certificate (with the cert wizard) you just have to connect and click with the right mouse click on your nick and choose register. Your certificate is linked then to your nick, and replaces a password.
