Just wander if somebody could advise me. I've recently deployed Lync 2013 infrastructure in one company and was really amazed how nice it is. Unfortunately Microsoft made it very expensive if you want to buy and install your own (around 200 Euro per each user!) and I absolutely don't like their cloud so started to looking for alternatives and found Jitsi. It looks really nice and is open source so price is perfect. However I'm not sure what configuration is the best to create something similar like Lync (I mean stability as well not only features).
I've found following options:
1. Jitsi Video bridge - not sure this will replace full functionality including chat.
2. Openfire with Videobridge plugin - seems to be still in beta/alpha stage so not sure should use in production
3. Other? Open source SIP server, Open source XMPP if so which will work correctly?
Any opinion how this will work in production? Any experience, advices, best practices?
