If you don't care too much for video conferencing why not use something like Mumble[0]. Super simple to install, super easy to maintain (even as your org grows and security rules get complex), supports as many users as you have bandwidth and quality is stellar and the code is open source. I feel sorry for anyone that has been stuck with Skype anytime after 2007. [0] Mumble: https://en.wikipedia.org/wiki/Mumble_(software) https://en.wikipedia.org/wiki/Mumble_(software)
