"Smooth Operator" - Creating a Playful Telephony Network with Asterisk - Part 1

This is the first in a series of videos explaining how to use "Asterisk" (https://www.asterisk.org/) open source communications software to create a complete, standalone local private branch exchange (PBX) network which can be used for playful telephone puzzles such as might be used in an escape room.

Example functionality includes:
- Hear pre-recorded or dynamically-generated messages when dialling different extension numbers – with easily configurable rules to create an almost limitless range of call destinations
- Step through a telephone menu tree, with sophisticated conditional logic, to hear an automated hint for a puzzle
- Dial a number or type a passcode on the telephone keypad to control physical devices, e.g. release a doorlock
- Trigger incoming phone calls by an external event or device, such as from an Arduino, which can deliver messages based on the value of a supplied variable
- Deliver a dynamically-generated voice message created using TTS synthesis
- A gamemaster or actor can call players from a control room to deliver clues or advance the narrative
- Integrate with external software, e.g. to record the phone conversation (or specific responses from it) and pass that to voice-recognition software

In this video, I demonstrate the core functionality of the system and describe the hardware required:
- Raspberry Pi ~ £35 (I'm using a fairly old Model B v2.0 with 512Mb RAM - newer models should run faster)
- Linksys PAP2T Analogue Telephone Adaptor ~£20
- Telephone handset with RJ11 connector (tone dial, not pulse dial)
- Relay, Maglock etc. as desired
