Proposal for a Federated Telecommunication System

My application for postpaid cellular phone service was recently denied, and what's worse, they just sent me an SMS saying so without any explanation why. Their very brief if not cryptic message further rubbed into my person that their time is more important than mine.

In frustration, I thought of an alternative: VoIP-based telecommunication infrastructure that any cellular phone or computing platform with VoIP and Wifi can connect to, call, chat and exchange email over. Thus, the idea of a federated telecommunication system is born. I will outline here a system architecture to build this infrastructure as far as my experience can guide me, hopefully you'd send in comments and suggestions to make this better. I hope you'd bear with me that it took me some time to go over this setback and also to refine and polish this article.
