For an excellent and disruption-free experience I use Mumble and if I have to WebRTC, but the browser experience isn&#x27;t as stable, performant and reliable. Nothing beats Mumble if video isn&#x27;t a requirement. You can join free Mumble servers, host your own or rent a server. It&#x27;s open source, so you&#x27;re not at the whim of a company and integration with your operating system is much better.<p>update 1: <a href="https:&#x2F;&#x2F;wiki.mumble.info&#x2F;wiki&#x2F;Features" rel="nofollow">https:&#x2F;&#x2F;wiki.mumble.info&#x2F;wiki&#x2F;Features</a>
It has encryption which cannot be disabled and the advanced audio features make it well suited for reliable and pleasant day to day use. It&#x27;s low-latency and instead of a centrally managed contact database like most commercial services have Mumble uses certificates for authentication and identification of your friends across servers.<p>update 2: There are alternative server implementations, one in C and another one in Go, meant to run on OpenWRT in terms of hardware requirements.
