FXS’s are a go!

Well its amazingly difficult to find documentation about how to make FXS’s work with Asterisk. I happen to have 4 FXS ports on the Cisco 3640, the same one that has four FXO ports. Below I’m including my configuration for use by others. The FXS port is configured as extension 600 (the Asterisk side configuration is also include).
