  I am using our shiny new Twilio Test account for the first time via CiviCRM and it doesn't go out.
  
  "The From phone number +12395995225 is not a valid, SMS capable inbound phone number or short code for your account. For more information, see
  [https://www.twilio.com/docs/errors/21606](https://www.twilio.com/doc/errors/21606)"
  
  The receiving phone number has been verified and using API calls via Twilio site works.
  
  What would be a good way to troubleshoot this?
