Fast payment- Call Tracking With Twilio & Wordpress. Track calls based on traffic sources

This tool is designed for marketers to track inbound calls based on traffic sources. The traffic sources include but are not limited to, Google Organic, Google adwords, Facebook, linkedin, other search engines, and specific marketing campaigns. Example: A person comes to the website from Google search, when the user lands on the site, the phone numbers change throughout the site, to the pre-set search phone number for google search traffic. (if we can get it down to the keyword level that would be fantastic) We want a plugin designed for wordpress widgets and shortcodes to insert phone numbers based on the source of traffic on the site. When the visitor comes from a traffic source, we would like a cookie dropped so when they come back to the site, we know they originally came from search. Google analytics and adwords conversion tracking too. As a part of this tracking, we want the call data to be pushed to an external api.
