TeamSpeak, currently in TeamSpeak 6 beta (build 6.0.0-beta4.1), is testing a new feature that lets two people make direct 1-1 calls without setting up or joining a server first. The alpha feature also includes built-in screensharing up to 4K, configurable presets for resolution/bitrate/FPS/audio, privacy controls, and picture-in-picture support for up to four feeds. Group calls are not yet confirmed, according to TeamSpeak's Community Manager, who said the scope hasn't been discussed since it wasn't the focus of this release. TeamSpeak has supported Linux, Windows, and macOS since its early versions and is not open source software.
Questions this post answers
Can I call someone on TeamSpeak without setting up a server?
Direct 1-1 calls are being tested for TeamSpeak 6 that let two people call each other without first setting up or joining a server. The feature is in alpha testing and not yet live, and comes bundled with built-in screensharing up to 4K, configurable resolution, bitrate, FPS and audio presets, privacy controls, and picture-in-picture support for up to four feeds. Developers weighing Discord alternatives can follow TeamSpeak's direct call rollout on daily.dev.
Does TeamSpeak 6 support group calls yet?
Group calls are not part of the direct calling feature being tested for TeamSpeak 6. TeamSpeak's Community Manager, SYOX, stated the initial feature focuses only on 1-1 private calls, and that whether and how group calls might be introduced later has not yet been scoped or discussed.
