Wakeup Calls (VoIP)

The Wakeup Call system is a fairly simple script that was written in PHP. To access the Wakeup Call function, we need to dial *62 from a device. The system will ask us for the time we would like to have our wakeup call. At the specified time, the system will ring our extension and play back the current music on-hold files.
This is a good example of an AGI script; to take a look at this or other scripts, we can look in the folder /var/lib/asterisk/agi-bin/.
