This app will show you how to build a call forwarding app that forwards calls during a specific time window and records voicemails if calls are unanswered or outside that time window.

How it works:

Call is placed to your Twilio number
Your app checks the time
If the time is within the defined window, it will forward the call to another phone number
If it is not in the defined time window, it will record a voicemail
