Presently, I am including students in the system such that while on campus they can benefit from free phone calls while on campus. Asterisk is really amazing.
Very reliable and the system can even work as a Windows VM. Since the UI is user friendly and heavily customizable, this is a very good product for small/medium size business.
It is a very stable and practical voice over ip system, you can integrate it with practically any system and the functionality is perfect.


Need to be careful not to leave it open to fraudulent calls. As a CLI based tool it can be a bit confusing to install from the tgz.
We use this everyday for our phones. We test a variety of platforms on a regular basis, but we have always stuck with Asterisk because it does everything we need.
It's difficult to set up, and some of the menu choices are very esoteric.
