I'm assuming it's $11.50 a month for a (limited) 25 max client TS3 server.
Hosting your own grants you 32 clients max, or an unlimited amount if you have an NPL/non-profit license. You could host that on a low-end VPS for $2-$5 a month.
Or Mumble, which is unlimited. VPS idea still stands for that too.
just sayin
