Twilio App - Emergency Anouncement

We are looking for a simple Twilio app that will prompt a caller to record a message, and then call out to another telephone number and replay the recorded message on repeat for some period of time (i.e. 3 minutes). This app just needs to be responsible for answering the call and then placing the outbound call. If we need to run code outside of Twilio it will need to be in a Docker container.
