Reschedule daily calls

[jlev]

When users sign up for daily calls, sometimes they are outside of normal office hours, or at a time that is not convenient for them every day. Let them adjust the time of day of their scheduled call, ideally via the keypad.

Interface ideas:

• if schedule exists: "press 9 to alter your daily call", then "press 1 for morning, 2 for afternoon, or 3 for evening", then "ok, we'll call you around X:XX every day. please hold for your daily call."
• if schedule does not exist: "press 9 to make a call every day", then same flow

Difficulties:

• requires an understanding of the user's location, to schedule in their local timezone
• cannot prompt for 12-hour time via 10-digit keypad
• speech to text is available via twilio, but expensive

Alternatives:

• let admins reschedule via the web interface

This would allow us to get around most issues:

• if schedule exists: "press 9 to alter your daily call", then "press 1" to move the call forward by one hour, or press 0 to move the call back by one hour"

Alternately, we could prompt users to press 1 for Eastern Time, press 2 for Central Time or press 3 for Pacific Time.

It seems like we CAN prompt for 12 hour time via 10-digit keypad as long as we keep it 4 digits, so that 1:30pm would be entered as 0130.

This gets pretty advanced. I'm not sure how many users would really need this much functionality, but if demand is strong enough I don't see why we can't provide this support.

Added an admin interface to edit scheduled call times in v1.4.2

This does not allow self-service, but the proposal for keypad entry still feel too clunky to me.
