The dial plan is the logic behind how phone calls are routed through your Asterisk installation. Asterisk runs
every incoming call, every outgoing call, and every call in between extensions through the dial plan logic in
order to determine where it should go and whether or not it should be completed.The dial plan is contained
in extensions.conf,and therefore it can be said that extensions.conf is easily the most important configuration file in Asterisk. Removing extensions.conf is similar to removing a traffic light at a complicated intersection; cars will want to enter and cars will want to leave, but there will be no way to direct them. extensions.conf is a bit more complicated than a typical configuration file. On top of the usual sections and settings, there is a logical flow similar to a program. Essentially, extensions.conf is one giant script.The sooner you keep this in mind, the easier it will be for you to write a good dial plan.
