Call Tracking with Ruby and Rails

This Ruby on Rails application demonstrates how to use Twilio for call tracking with marketing channels. The application allows users to search for available phone numbers, purchase them, forward incoming calls to a salesperson, and display charts showing data about the phone numbers and calls they receive. The backend part of the code creates a LeadSource as well as a Twilio Number and associates it with a lead source in the database. The frontend uses jQuery and Chart.js to fetch call tracking statistics from the server and display them in colorful pie charts.
