I remember moving to mumble from teams peak because it allowed pretty cool levels of configuration.

Back in the late 00s and early 00s I was doing world of warcraft raiding. I had the server setup to have one key for main raid and another to talk to only officers. Quite useful especially in bigger raids.

Also as I recall for any remotely large ts server you needed to pay. The self hosted one was always gimped. Mumble you could self host with no limits.

Also supports positional audio which was very cool wheb first introduced for voip

Can confirm. Goonswarm still needs Mumble because we have thousands of players that need to listen to the weekly fireside.
