extensions.conf

At the center of every good universe is a dialplan. The extensions.conf file is the means by which you tell Asterisk how you want calls to be handled. The dialplan contains a list of instructions that, unlike traditional telephony systems, is entirely customizable. The dialplan is so important that rather than defining it in this appendix, we have dedicated all of Dialplan Basics and More Dialplan Concepts, as well as Application Reference, to this topic. Go forth, read, and enjoy!
