This app allows you to view and pickup parked calls, by clicking them on the screen.
You can also see and call the person who parked the call.
Clone the repository to your Monster UI apps directory (often /var/www/html/monster-ui/apps, but may be different on your system). Then you may register the app on KAZOO with a sup command (with your specific Crossbar API location):
cd /var/www/html/monster-ui/apps
git clone https://github.com/ruhnet/monster-ui-parkinglot parkinglot
sup crossbar_maintenance init_app '/var/www/html/monster-ui/apps/parkinglot' \
