; extensions.conf - the Asterisk dial plan;; Static extension configuration file, used by; the pbx_config module. This is where you configure all your ; inbound and outbound calls in Asterisk. ; ; This configuration file is reloaded ; - With the "dialplan reload" command in the CLI; - With the "reload" command (that reloads everything) in the CLI;; The "General" category is for certain variables. ;[general];; If static is set to no, or omitted, then the pbx_config will rewrite; this file when extensions are modified. Remember that all comments; made in the file will be lost when that happens. ;; XXX Not yet implemented XXX;static=yes;; if static=yes and writeprotect=no, you can save dialplan by; CLI command "dialplan save" too;writeprotect=no;; If autofallthrough is set, then if an extension runs out of; things to do, it will terminate the call with BUSY, CONGESTION; or HANGUP depending on Asterisk's best guess. This is the default.;; If autofallthrough is not set, then if an extension runs out of ; things to do, Asterisk will wait for a new extension to be dialed ; (this is the original behavior of Asterisk 1.0 and earlier).;;autofallthrough=no;; If clearglobalvars is set, global variables will be cleared ; and reparsed on an extensions reload, or Asterisk reload.;; If clearglobalvars is not set, then global variables will persist; through reloads, and even if deleted from the extensions.conf or; one of its included files, will remain set to the previous value.;; NOTE: A complication sets in, if you put your global variables into; the AEL file, instead of the extensions.conf file. With clearglobalvars; set, a "reload" will often leave the globals vars cleared, because it; is not unusual to have extensions.conf (which will have no globals); load after the extensions.ael file (where the global vars are stored).; So, with "reload" in this particular situation, first the AEL file will; clear and then set all the global vars, then, later, when the extensions.conf; file is loaded, the global vars are all cleared, and then not set, because; they are not stored in the extensions.conf file.;clearglobalvars=no;; If priorityjumping is set to 'yes', then applications that support; 'jumping' to a different priority based on the result of their operations; will do so (this is backwards compatible behavior with pre-1.2 releases; of Asterisk). Individual applications can also be requested to do this; by passing a 'j' option in their arguments.;;priorityjumping=yes;; User context is where entries from users.conf are registered.
