Programming VoIP phones for Asterisk using FreePBX

This is a how to video demonstrating how to configure a SIP compliant phone ( Cisco SPA504 ) to work with a VoIP install. In this video, I am using PBX in a Flash with IncrediblePBX installed. This uses FreePBX as its web interface and makes configuration easy. Anyone using Elastix will have a similar configuration just by clicking on the PBX tab from the main screen.
