This is an example app that:

• Uses Twilio Add-ons from the Twilio Add-ons Marketplace to block unwanted voice calls
• Integrates 3 spam Add-ons from the Marketplace (Whitepages Pro Phone Reputation, Marchex Clean Call, and Nomorobo Spam Score)

How it works:

• When your Twilio number receives an inbound call, this code will check the spam rating of the phone number on all 3 spam Add-ons
• If all 3 Add-ons deem the number to be spam, the number will be blocked
• If the number is not deemed spam, the call will be forwarded to the customer
