Handle

• [ ] Upon notification via POST, if a new call, display details, display routing from the station the display resides at to the location in the call details, start a countdown timer (from 90 seconds).
• [ ] Upon notification via POST of an existing call, update the routing if the location details were not previously present, or have changed.
• [ ] At some point remove the call.
• [ ] Be able to accommodate multiple calls at the same time.
• [ ] Location data may be a Lat/Lon if from a cell phone.

Possible Design

Web server runs node. Planetpress posts all information to server. Server uses websockets to notify station/update display.

# Questions

1. Can there be multiple call types, or just one per call?
1. Do stations need to register their display with the server?
1. How do we restrict displays to stations?  (ip segment)
1. When should the call be cleared from the display?
1. What should be on the display when no calls are active?
