Twilio is a cloud communication platform that enables developers to build and deploy real-time communication applications. In this article, Dominik Kundel demonstrates how to build a basic call center in just 10 minutes using TwiML Bins, a feature of the Twilio platform. The author creates two TwiML Bins: "Join Queue" to add callers to the queue and "Work Off Queue" to connect them with an available agent. Using the Twilio Node.js helper library, the author builds a script that initiates a call from one phone number to another using the second TwiML Bin. The script is executed by passing in the recipient's phone number as a command-line argument, allowing users to build and test their own call centers with minimal setup.
