Server installation is deceptively easy, client installation is a bit more difficult because you must configure your audio installation. Nothing difficult for someone curious enough.
After that, all your audio communications will be a breeze. It's fast, it's low on resources, you don't even need to think about it (it doesn't hog your DSL line and when your DSL line _is_ full, you can still have some reasonable conversation), it's using Opus now so the quality is excellent, the client is available on Windows and Linux at least (I have regular conversation using these 2 OSes, no problem to report) and there are prototypes for Android, it's secure (to the extent that you must trust the server), it's multiparty, and it's Libre.

Only nitpick: it's its own standard.
