+; 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 extenpatternmatchnew is set (true, yes, etc), then a new algorithm that uses
+; a Trie to find the best matching pattern is used. In dialplans
+; with more than about 20-40 extensions in a single context, this
+; new algorithm can provide a noticeable speedup.
+; With 50 extensions, the speedup is 1.32x
+; with 88 extensions, the speedup is 2.23x
+; with 138 extensions, the speedup is 3.44x
+; with 238 extensions, the speedup is 5.8x
+; with 438 extensions, the speedup is 10.4x
+; With 1000 extensions, the speedup is ~25x
+; with 10,000 extensions, the speedup is 374x
+; Basically, the new algorithm provides a flat response
+; time, no matter the number of extensions.
+;
+; By default, the old pattern matcher is used.
+;
+; ****This is a new feature! *********************
+; The new pattern matcher is for the brave, the bold, and
+; the desperate. If you have large dialplans (more than about 50 extensions
+; in a context), and/or high call volume, you might consider setting
+; this value to "yes" !!
+; Please, if you try this out, and are forced to return to the
+; old pattern matcher, please report your reasons in a bug report
+; on bugs.digium.com. We have made good progress in providing something
+; compatible with the old matcher; help us finish the job!
+;
+; This value can be switched at runtime using the cli command "dialplan set extenpatternmatchnew true"
+; or "dialplan set extenpatternmatchnew false", so you can experiment to your hearts content.
+;
+;extenpatternmatchnew=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=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. 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.

+;exten => someexten,{priority|label{+|-}offset}[(alias)],application(arg1,arg2,...)
+;exten => someexten,{priority|label{+|-}offset}[(alias)],application,arg1|arg2...
+;
+; Timing list for includes is
+;
+; <time range>|<days of week>|<days of month>|<months>
+;
+; Note that ranges may be specified to wrap around the ends. Also, minutes are
+; fine-grained only down to the closest even minute.
