Win, nix, android video in the inside network — is it possible?

You need to check that this works better with video. Well, then implement.

Add about customers. Jabber itself then you do not need, you can use a Softphone like X-Lite ( or the paid version of Bria) well many others ( Google is easy) with video support.

If you need a purely video conferencing, the software is for telephony-enabled video calls not quite right for you. Well, you can adapt, but it will look like a spike.
