We're going to build a basic PBX system today that will let you have multiple users, each with their own phone number, and also give them the ability to handle calls.

This will serve as a basic Google Voice type system.

We're going to cover how to set up each user account with their own subaccount at Twilio and assign each subaccount with a phone number.

We're also going to set those phone numbers up to call the user's registered phone number, allowing the user to see a log of incoming calls and use "Click-to-Call" for those incoming phone numbers, and finally we're going to show you how to delete the user from your site.

We're also going to use a handy PHP micro framework called Jolt to build this application.
