"Ringdown" Function Template

[kwhinnery]

A common need for event organizers is to provide a hotline for attendees to call which will dial a list of organizers' phone numbers until one of them picks up. Create a Function which loads a list of comma separated phone numbers, in E.164 format, from an environment variable RINGDOWN_PHONE_NUMBERS. When a call comes in, create TwiML which dials each number in the list until a call is connected. Provide a <Say> fallback in the case no call is connected.
