;! ;! Automatically generated configuration file ;! Filename: extensions.conf (/etc/asterisk/extensions.conf) ;! Generator: Manager ;! Creation Date: Fri Aug 1 15:09:40 2008 ;! [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. The ; default value is 'default' ; ;userscontext=default ; ; You can include other config files, use the #include command ; (without the ';'). Note that this is different from the "include" command ; that includes contexts within other contexts. The #include command works ; in all asterisk configuration files. ;#include "filename.conf" ; The "Globals" category contains global variables that can be referenced ; in the dialplan with the GLOBAL dialplan function: ; ${GLOBAL(VARIABLE)} ; ${${GLOBAL(VARIABLE)}} or ${text${GLOBAL(VARIABLE)}} or any hybrid ; Unix/Linux environmental variables can be reached with the ENV dialplan ; function: ${ENV(VARIABLE)} ; [globals] CONSOLE = Console/dsp ; Console interface for demo ;CONSOLE=Zap/1 ;CONSOLE=Phone/phone0 IAXINFO = guest ; IAXtel username/password ;IAXINFO=myuser:mypass TRUNK = Zap/G2 ; Trunk interface ; ; Note the 'G2' in the TRUNK variable above. It specifies which group (defined ; in zapata.conf) to dial, i.e. group 2, and how to choose a channel to use in ; the specified group. The four possible options are: ; ; g: select the lowest-numbered non-busy Zap channel ; (aka. ascending sequential hunt group). ; G: select the highest-numbered non-busy Zap channel ; (aka. descending sequential hunt group). ; r: use a round-robin search, starting at the next highest channel than last ; time (aka. ascending rotary hunt group). ; R: use a round-robin search, starting at the next lowest channel than last ; time (aka. descending rotary hunt group). ; TRUNKMSD = 1 ; MSD digits to strip (usually 1 or 0) trunk_1_cid = asreceived trunk_1 = Zap/g2 trunk_2_cid = unknown trunk_2 = SIP/trunk_2 ;TRUNK=IAX2/user:pass@provider ; ; Any category other than "General" and "Globals" represent ; extension contexts, which are collections of extensions. ; ; Extension names may be numbers, letters, or combinations ; thereof. If an extension name is prefixed by a '_' ; character, it is interpreted as a pattern rather than a ; literal. In patterns, some characters have special meanings: ; ; X - any digit from 0-9 ; Z - any digit from 1-9 ; N - any digit from 2-9 ; [1235-9] - any digit in the brackets (in this example, 1,2,3,5,6,7,8,9) ; . - wildcard, matches anything remaining (e.g. _9011. matches ; anything starting with 9011 excluding 9011 itself) ; ! - wildcard, causes the matching process to complete as soon as ; it can unambiguously determine that no other matches are possible ; ; For example the extension _NXXXXXX would match normal 7 digit dialings, ; while _1NXXNXXXXXX would represent an area code plus phone number ; preceded by a one. ; ; Each step of an extension is ordered by priority, which must ; always start with 1 to be considered a valid extension. The priority ; "next" or "n" means the previous priority plus one, regardless of whether ; the previous priority was associated with the current extension or not. ; The priority "same" or "s" means the same as the previously specified ; priority, again regardless of whether the previous entry was for the ; same extension. Priorities may be immediately followed by a plus sign ; and another integer to add that amount (most useful with 's' or 'n'). ; Priorities may then also have an alias, or label, in ; parenthesis after their name which can be used in goto situations ; ; Contexts contain several lines, one for each step of each ; extension, which can take one of two forms as listed below, ; with the first form being preferred. ; ;[context] ;exten => someexten,{priority|label{+|-}offset}[(alias)],application(arg1,arg2,...) ;exten => someexten,{priority|label{+|-}offset}[(alias)],application,arg1|arg2... ; ; Included Contexts ; ; One may include another context in the current one as well, optionally with a ; date and time. Included contexts are included in the order ; they are listed. ; The reason a context would include other contexts is for their ; extensions. ; The algorithm to find an extension is recursive, and works in this ; fashion: ; first, given a stack on which to store context references, ; push the context to find the extension onto the stack... ; a) Try to find a matching extension in the context at the top of ; the stack, and, if found, begin executing the priorities ; there in sequence. ; b) If not found, Search the switches, if any declared, in ; sequence. ; c) If still not found, for each include, push that context onto ; the top of the context stack, and recurse to a). ; d) If still not found, pop the entry from the top of the stack; ; if the stack is empty, the search has failed. If it's not, ; continue with the next context in c). ; This is a depth-first traversal, and stops with the first context ; that provides a matching extension. As usual, if more than one ; pattern in a context will match, the 'best' match will win. ; Please note that that extensions found in an included context are ; treated as if they were in the context from which the search began. ; The PBX's notion of the "current context" is not changed. ; Please note that in a context, it does not matter where an include ; directive occurs. Whether at the top, or near the bottom, the effect ; will be the same. The only thing that matters is that if there is ; more than one include directive, they will be searched for extensions ; in order, first to last. ; Also please note that pattern matches (like _9XX) are not treated ; any differently than exact matches (like 987). Also note that the ; order of extensions in a context have no affect on the outcome. ; ; Timing list for includes is ; ;
