While I was hoping to see something freeswitch-based when I clicked through, with how affordable Plivo and Twilio are, it really doesn't make much sense to try and run your own setup, unless you have something very custom to do or are looking to build a business and potentially scale up quite a bit. From the readme, it appears that this project is tackling some of the most common use cases and provides a nice UI. Great job! Also, a live demo would be nice if you are looking to build a user base.
