4 Asterisk has the ability to initiate a call from outside of the normal
5 methods such as the dialplan, manager interface, or spooling interface.
7 Using the call file method, you must give Asterisk the following information:
9 * How to perform the call, similar to the Dial() application
10 * What to do when the call is answered
12 With call files you submit this information simply by creating a file with
13 the required syntax and placing it in the outgoing spooling directory, located
14 by default in /var/spool/asterisk/outgoing/ (configurable in asterisk.conf).
16 The pbx_spool module aggressively examines the directory contents every second,
17 creating a new call for every call file it finds. Do NOT write or create
18 the call file directly in the outgoing directory, but always create the file
19 in another directory of the same filesystem and then move the file to the
20 /var/spool/asterisk/outgoing directory, or Asterisk may read just a partial
27 The call file consists of <Key>: <value> pairs; one per line.
29 Comments are indicated by a '#' character that begins a line, or follows a space
30 or tab character. To be consistent with the configuration files in Asterisk,
31 comments can also be indicated by a semicolon. However, the multiline comments
32 (;-- --;) used in Asterisk configuration files are not supported. Semicolons can
33 be escaped by a backslash.
36 The following keys-value pairs are used to specify how setup a call:
38 Channel: <channel> the channel to use for the new call, in the form
39 technology/resource as in the Dial application. This
42 Callerid: <callerid> the caller id to use.
44 WaitTime: <number> how many seconds to wait for an answer before the call
45 fails (ring cycle). Default 45 seconds.
47 Maxretries: <number> number of retries before failing, not including the
48 initial attempt. Default = 0 e.g. don't retry if fails.
50 RetryTime: <number> how many seconds to wait before retry. The default is
53 Account: <account> the account code for the call. This value will be
54 assigned to CDR(accountcode)
58 When the call answers there are two choices:
59 * Execute a single application, or
60 * Execute the dialplan at the specified context/extension/priority.
63 To execute an application:
64 --------------------------
66 Application: <appname> the application to execute
68 Data: <args> the application arguments
71 To start executing applications in the dialplan:
72 ------------------------------------------------
74 Context: <context> the context in the dialplan
76 Extension: <exten> the extension in the specified context
78 Priority: <priority> the priority of the specified extension
83 Setvar: <var=value> you may also assign values to variables that will be
84 available to the channel, as if you had performed a
85 Set(var=value) in the dialplan. More than one Setvar:
89 The processing of the call file ends when the call is answered and terminated; when
90 the call was not answered in the initial attempt and subsequent retries; or if
91 the call file can't be successfully read and parsed.
93 To specify what to do with the call file at the end of processing:
95 Archive: <yes|no> if "no" the call file is deleted. If set to "yes" the
96 call file is moved to the "outgoing_done" subdirectory
97 of the Asterisk spool directory. The default is to
101 If the call file is archived, Asterisk will append to the call file:
103 Status: <exitstatus> can be "Expired", "Completed" or "Failed"
107 Other lines generated by Asterisk:
109 Asterisk keep track of how many retries the call has already attempted,
110 appending to the call file the following key-pairs in the form:
112 StartRetry: <pid> <retrycount> (<time>)
113 EndRetry: <pid> <retrycount> (<time>)
115 With the main process ID (pid) of the Asterisk process, the retry number, and
116 the attempts start and end times in time_t format.
123 <astspooldir>/outgoing the outgoing dir, where call files are put
126 <astspooldir>/outgoing_done the archive dir
129 <astspooldir> is specified in asterisk.conf, usually /var/spool/asterisk
133 How to schedule a call
134 ======================
136 Call files that have the time of the last modification in the future are ignored
137 by Asterisk. This makes it possible to modify the time of a call file to the
138 wanted time, move to the outgoing directory, and Asterisk will attempt to
139 create the call at that time.
