Appendix A is a jargon buster.
Appendix B takes a quick look at how to configure Free World Dialup (FWD)
services for your AsteriskNOW PBX system. If you have multiple offices,

inter-office communications.
Appendix C shows how a service provider can modify the AsteriskNOW distribution
to add their own service provider entry directly into the AsteriskNOW GUI.
