Since this was made, TeamSpeak has effectively taken a total sh** - TS3/TS5 is dead and highly unlikely resurrectable although I try haha.
Meanwhile Discord has done just about the opposite, on an exponentially larger scale with more stability.. notice TeamSpeak dies like \__ and Discord is up / / /:
Discord went head on with competitors such as Slack, Curse, Twitch, bigo, TeamSpeak, and others with plentiful success. This is namely due to their business model involving VC (venture capital). They were able to raise over $20,000,000 in relatively little time.
When you have $20,000,000 it is hard to make a VoIP client and server platform that does not work. Needless to say they started off with crashes from time to time but quickly learned to scale up into the cloud.
tl;dr this plugin is old, TeamSpeak is old, and this community is now old.
I need to probably consider diving deeply into another market like Discord and start writing plugins, researching security, and whatever else more involved in a product that has not lost 75% interest in just a handful of years.
