Twilio has released TwiML Bins, which allow users to create simple programmable phone numbers and hotlines without setting up a server. With these bins, developers can build their own hotlines in just five minutes, including one for the popular character Hodor from Game of Thrones. To get started, users need to sign up for a free Twilio account and follow three steps: writing code to respond to text messages and phone calls, buying a programmable phone number, and setting up TwiML bins. The process is easy and can be completed in just five minutes, making it accessible to developers with no prior coding experience. Once set up, users can customize their hotlines to perform various tasks, such as playing audio files or forwarding calls to other numbers.
