There are a number of variables that are defined or read
by Asterisk. Here is a listing of them. More information is available
in each application's help text. All these variables are in UPPER CASE
only.
Variables marked with a * are builtin functions and can't be set, only read in the dialplan. Writes to such variables are silently ignored.
