This is the second in a series of videos explaining how to use "Asterisk" (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.

Part Two: youtu.be/4G4u-2mDtCY
Part Three: youtu.be/QDOD_sBffRI

In this video, I'll explain how to download and configure RasPBX, which is a complete standalone distribution including the Asterisk server on a Raspbian OS, and the FreePBX web GUI. I'll talk through setting up the OS itself, creating extensions in Asterisk via the FreePBX GUI, and then mapping those extensions to a physical phone handset connected through a Linksys PAP2T ATA, and a virtual softphone using MicroSIP (microsip.org)
