Asterisk call files
|
||||
===================
|
||||
|
||||
Asterisk has the ability to initiate a call from outside of the normal
|
||||
methods such as the dialplan, manager interface, or spooling interface.
|
||||
|
||||
Using the call file method, you must give Asterisk the following information:
|
||||
|
||||
* How to perform the call, similar to the Dial() application
|
||||
* What to do when the call is answered
|
||||
|
||||
With call files you submit this information simply by creating a file with
|
||||
the required syntax and placing it in the outgoing spooling directory, located
|
||||
by default in /var/spool/asterisk/outgoing/ (configurable in asterisk.conf).
|
||||
|
||||
The pbx_spool module aggressively examines the directory contents every second,
|
||||
creating a new call for every call file it finds. Do NOT write or create
|
||||
the call file directly in the outgoing directory, but always create the file
|
||||
in another directory of the same filesystem and then move the file to the
|
||||
/var/spool/asterisk/outgoing directory, or Asterisk may read just a partial
|
||||
file.
|
||||
|
||||
|
||||
The call file syntax
|
||||
====================
|
||||
|
||||
The call file consists of <Key>: <value> pairs; one per line.
|
||||
|
||||
Comments are indicated by a '#' character that begins a line, or follows a space
|
||||
or tab character. To be consistant with the configuration files in Asterisk,
|
||||
comments can also be indicated by a semicolon. However, the multiline comments
|
||||
(;-- --;) used in Asterisk configuration files are not supported. Semicolons can
|
||||
be escaped by a backslash.
|
||||
|
||||
|
||||
The following keys-value pairs are used to specify how setup a call:
|
||||
|
||||
Channel: <channel> the channel to use for the new call, in the form
|
||||
technology/resource as in the Dial application. This
|
||||
value is required.
|
||||
|
||||
Callerid: <callerid> the caller id to use.
|
||||
|
||||
WaitTime: <number> how many seconds to wait for an answer before the call
|
||||
fails (ring cycle). Default 45 seconds.
|
||||
|
||||
Maxretries: <number> number of retries before failing, not including the
|
||||
initial attempt. Default = 0 e.g. don't retry if fails.
|
||||
|
||||
RetryTime: <number> how many seconds to wait before retry. The default is
|
||||
300 (5 minutes).
|
||||
|
||||
Account: <account> the account code for the call. This value will be
|
||||
assigned to CDR(accountcode)
|
||||
|
||||
|
||||
|
||||
When the call answers there are two choices:
|
||||
* Execute a single application, or
|
||||
* Execute the dialplan at the specified context/extension/priority.
|
||||
|
||||
|
||||
To execute an application:
|
||||
--------------------------
|
||||
|
||||
Application: <appname> the application to execute
|
||||
|
||||
Data: <args> the application arguments
|
||||
|
||||
|
||||
To start executing applications in the dialplan:
|
||||
------------------------------------------------
|
||||
|
||||
Context: <context> the context in the dialplan
|
||||
|
||||
Extension: <exten> the extension in the specified context
|
||||
|
||||
Priority: <priority> the priority of the specified extension
|
||||
(numeric or label)
|
||||
|
||||
|
||||
|
||||
Setvar: <var=value> you may also assign values to variables that will be
|
||||
available to the channel, as if you had performed a
|
||||
Set(var=value) in the dialplan. More than one Setvar:
|
||||
maybe specified.
|
||||
|
||||
|
||||
The processing of the call file ends when the call is answered and terminated; when
|
||||
the call was not answered in the initial attempt and subsequent retries; or if
|
||||
the call file can't be successfully read and parsed.
|
||||
|
||||
To specify what to do with the call file at the end of processing:
|
||||
|
||||
Archive: <yes|no> if "no" the call file is deleted. If set to "yes" the
|
||||
call file is moved to the "outgoing_done" subdirectory
|
||||
of the Asterisk spool directory. The default is to
|
||||
delete the call file.
|
||||
|
||||
|
||||
If the call file is archived, Asterisk will append to the call file:
|
||||
|
||||
Status: <exitstatus> can be "Expired", "Completed" or "Failed"
|
||||
|
||||
|
||||
|
||||
Other lines generated by Asterisk:
|
||||
|
||||
Asterisk keep track of how many retries the call has already attempted,
|
||||
appending to the call file the following key-pairs in the form:
|
||||
|
||||
StartRetry: <pid> <retrycount> (<time>)
|
||||
EndRetry: <pid> <retrycount> (<time>)
|
||||
|
||||
With the main process ID (pid) of the Asterisk process, the retry number, and
|
||||
the attempts start and end times in time_t format.
|
||||
|
||||
|
||||
|
||||
Directory locations
|
||||
===================
|
||||
|
||||
<astspooldir>/outgoing the outgoing dir, where call files are put
|
||||
for processing
|
||||
|
||||
<astspooldir>/outgoing_done the archive dir
|
||||
|
||||
|
||||
<astspooldir> is specified in asterisk.conf, usually /var/spool/asterisk
|
||||
|
||||
|
||||
|
||||
How to schedule a call
|
||||
======================
|
||||
|
||||
Call files that have the time of the last modification in the future are ignored
|
||||
by Asterisk. This makes it possible to modify the time of a call file to the
|
||||
wanted time, move to the outgoing directory, and Asterisk will attempt to
|
||||
create the call at that time.
