Asterisk dialplan functions example

Asterisk dialplan functions example. Dialplan functions allow you to calculate string lengths, dates and times, MD5 checksums, and so on, all from within a dialplan expression. The hook dialplan will have two variables available. There are also dialplan functions which allow you to manipulate location information as it's passed through the dialplan. Overview - Asterisk Documentation. conf' is set to 'no Jan 1, 2013 · 6. 1. External IVR Interface. exten => 1,1,Answer () same => n,Set (CONFBRIDGE (user,template)=my_user) same => n,Set (CONFBRIDGE (user,admin same => n,ConfBridge(1) This example shows how to use a predefined user profile in confbridge. format - This is for the format of the file. Certified Asterisk 18. Conferencing Applications. Asterisk 19 Documentation. Record (dialplan application) 1. Each section defines configuration for a configuration object within res_pjsip or an associated module. f - Returns billsec or duration fields as floating point values. Here is an example of setting the userfield for a channel: exten => 101,1,Set(CHANNEL(userfield)=I like waffles!) DUNDi Dialplan Functions. This means that the Asterisk dialplan— like any programming language— recognizes symbols called operators that allow you to manipulate variables. Hopefully this helps! There are plenty of examples on that voip-info page that should be able to help you along! Dialplan Functions. MATH (dialplan function) - NEW. pjsip. same => n,Set(VOLUME(RX)=2) Example: Increase volume with DTMF control. Purpose and usage. same => n,Set(CONFBRIDGE(user,template)=my_user) same => n,Set(CONFBRIDGE(user,admin)=yes) . For example, Lua 5. Example: Increase volume. Many applications that perform the same operation as a corresponding function will - Selection from Asterisk: The Future of Telephony [Book] When you create an Asterisk dialplan, you’re really writing code in a specialized scripting language. If you call PJSIP_RESPONSE_HEADER in a normal dialplan context you'll be operating on the caller's (incoming) channel which may not be what you want. Count the number of voicemails in a specified mailbox, you could also specify the mailbox folder. This example shows how to use a predefined user profile in confbridge. If a filename passed to MixMonitor ends with '. These applications are then scripted sequentially in the dialplan. Asterisk Queues. same => n,Set(CONFBRIDGE(user,template)=my_user) same => n,Set(CONFBRIDGE(user,admin)=yes) Dialplan Functions and Applications¶ HANGUPCAUSE_KEYS¶ Used to obtain a comma separated list of all channels for which hangup causes are available. Everything should be made as simple as possible, but not simpler. Example: The 'varname' parameter can only accept a variable name, not a variable expression. This application will set the current context, extension, and priority in the channel structure based on the evaluation of the given condition. Once you have ensured that these have been selected, save your changes ('x' key if using curses-based menuselect or select the "Save & Exit" option if using newt-based or gtk-based Description. To operate on the callee's (outgoing) channel call PJSIP_HEADER in a pre-dial handler. After restarting dongle0, incoming calls will start dialplan from exten. AGI Commands. For example, reading the SHELL() function can execute arbitrary commands on the system Asterisk is running on. Example: Set (junky=$ {RAND (1,8)}); Sets junky to a random number between 1 and 8, inclusive. Example: Add 2 endpoints to a dial group. 9 and above. 9 Documentation. Sophisticated subroutines that help you manipulate data in a variety of ways. MIXMONITOR_FILENAME - Will contain the filename used to record. conf is a flat text file composed of sections like most configuration files used with Asterisk. Jun 8, 2019 · It have really limited number of options. id - The unique ID of the MixMonitor instance. Syntax: Set (TIMEOUT (response)=value) List of the possible options. PJSIP_HEADER_PARAM allows you to read or set parameters in a SIP header on a PJSIP channel. 2. Less Clutter¶. Nov 10, 2005 · Using Functions in Asterisk Dialplans. The command supplied to this function will be executed by the system's shell, typically specified in the SHELL environment variable. HOOK_ID is the hook ID for enabling or disabling the hook. Variables are referenced in the dialplan (extensions. wav49', Asterisk will silently convert the extension to '. lua files can be found below. The TIMEOUT (response) function is one of those new functions which will replace the old applications. To operate on the callee's (outgoing) channel call PJSIP_RESPONSE_HEADER in a pre-connect handler. same => n,Set(VOLUME(TX)=3) Example: Increase volume. same => n,Set(VOLUME(TX,p)=3) Pattern matching allows us to create extension patterns in our dialplan that match more than one possible dialed number. Description. Ensure that you can select res_curl and res_config_curl from the "Resource Modules" menu and that you can select func_curl from the "Dialplan Functions" menu. Lua Dialplan Examples. To refer to the variable's value, enclose it inside ${}. The CALLERID information is passed during the initial call setup. While somewhat simple and primitive, it’s a good example for learning about conditional branching within the Asterisk dialplan. conf as a template for a dynamic profile. exten => 1,1,Set(DIALGROUP(mygroup,add)=SIP/10) Arguments¶. Let’s assume for the sake of this example that the victim’s phone number is 888-555-1212: Jan 3, 2013 · If you want to use regex (regular expressions), Asterisk 1. exten => addheader,1,Set(PJSIP_HEADER(add,X-MyHeader)=myvalue) If 'live_dangerously' in 'asterisk. channel direction - Direction can be either 'rx', 'tx', or 'both'. The PRESENCE_STATE function can be used to retrieve the presence from any presence provider. 0 or one of the enum values listed below. Dialplan functions allow you to add more power to your expressions; you can think of them as intelligent variables. 29. Asterisk functions are very similar to functions in many programming languages. Callable from within dialplan and Asterisk's various interfaces. MIXMONITOR_FILENAME will contain the actual filename that Asterisk is writing to, not necessarily the value that was passed in. Dialplan Functions Dialplan functions are not a new concept. The labels are specified with the same syntax as used within the Upgrading to Asterisk 16. The direction can either be set to a valid floating point number between 0. The application modules provide call functionality to the system. Table of contents. This example uses the CALLERID function, which allows us to retrieve the caller ID information on the inbound call. Let’s assume for the sake of this example that the victim’s phone number is 888-555-1212: It runs asynchronously on a new channel. MATH - this function allows you to perform simple mathematical operations. Dialplan Functions and Applications¶ HANGUPCAUSE_KEYS¶ Used to obtain a comma separated list of all channels for which hangup causes are available. There are variables that are automatically introduced by Asterisk, and you have the freedom to add your own depending on your needs. Thus, we would write the above two examples like this: $[${COUNT} + 1] $[${COUNT} / 2] When Asterisk encounters an expression in a dialplan, it replaces the entire expression with the resulting value. They demonstrate various ways to organize extensions. The unique ID can be retrieved through the channel variable used as an argument to the i option to MixMonitor. NOTE: Information about the Asterisk functions could be obtained by typing the show functions command. The Asterisk dialplan is specified in the configuration file named extensions. 3. This, the unary minus operator, is right associative, and has the same precedence as the ! operator. For example: NoOp (SIP/mypeer has presence $ {PRESENCE_STATE (SIP/mypeer,value)}) NoOp (Conference number 1234 has presence message $ {PRESENCE_STATE (MeetMe:1234,message)}) The PRESENCE_STATE function can also be used to set custom presence state from If 'live_dangerously' in 'asterisk. exten => 7000,1,Verbose("We are going to run a Gosub before Dialing!") same => n,Gosub(my-gosub,s,1) Interacting with Asterisk from Lua (apps, variables, and functions) Lua Dialplan Examples ; Lua Dialplan Hints ; Lua Dialplan Tips and Tricks Lua Dialplan Tips and Tricks Table of contents . Example: Mailbox folder count. BUILD_HOSTNAME - The string representing the name of the For a process-based AGI application or a connection to a FastAGI server, the variables listed in Table 21. Other common locations for this file include /usr/local/etc/asterisk/ and /opt/etc/asterisk/. conf) using the syntax ${foo:offset:length} Return the result of subtracting expr1 from 0. Syntax ¶ FILE(filename,offset,length,options,format) If you call PJSIP_HEADER in a normal dialplan context you'll be operating on the caller's (incoming) channel which may not be what you want. 6. if the audio is voice, the voices will sound squeaky sort of like obnoxious Syntax. info - The possible values are: ASTERISK_VERSION_NUM - A string of digits is returned, e. [handler] exten => readheader,1,NoOp (PJSIP_RESPONSE 6. Check out the old syntax of the SetCIDNum application here. If the skip field is negative, Asterisk will instead return the specified number of digits from the end of the number. Special Asterisk Dialplan Extensions. After this application completes, the pbx engine will continue dialplan execution at the specified location in the dialplan. conf, this is not a problem. exten => +79139131234,1,Noop() Within each context, we can define one or more extensions. In the above example, ${TOLOWER(${MAC})}. Dialplan Syntax. AGI environment variables. The CALLERID (all) function is one of those new functions which will replace the old applications. Instead of defining every extension inline, you can use this method to create a neater extensions. Dialplan Applications. When Alice dials a number on her phone, Asterisk first looks for an extension (in the context Upgrading to Asterisk 20. Asterisk REST Interface. 1 - OMIT. Similarly, disposition and amaflags will return Note. cfg would define a relative URI to be served that matches the format of MACADDRESS. However, depending on the channel technology, the caller name may be delayed. 10602 for 1. accountcode - R/W the channel's account code. Example of a Variable. exten => number,priority,application([parameter[,parameter2]]) Let's look at an example extension. Return the result of a logical complement of expr1. It is opensource, you can add your function into source code (minimal c/c++ experience under linux is required). Asterisk applications, variables or functions whose names conflict with Lua reserved words or contain special characters must be referenced using the [] operator. For example, Set takes as the first argument (before the =) a variable name, so: It runs asynchronously on a new channel. g. There are many different system shells available with somewhat different behaviors, so the output generated by this function may vary between platforms. 0, or 999999 when using a Git build. For example, 'start', 'answer', and 'end' will be retrieved as epoch values, when the 'u' option is passed, but formatted as YYYY-MM-DD HH:MM:SS otherwise. conf. 66. Dialplan functions are somewhat similar to dialplan applications, but instead of doing work on a particular channel or call, they simply retrieve or set a particular setting on a channel, or perform text manipulation. dongle cmd dongle0 AT+CPBS=\"ON\" dongle cmd dongle0 AT+CPBW=1,\"+79139131234\",145. The DUNDIQUERY and DUNDIRESULT dialplan functions will let you initiate a DUNDi query from the dialplan, see how many results there are, and access each one. Sections are identified by names in square brackets. For example, if NUMBER were set to a value of 98765, then ${NUMBER:2} would tell Asterisk to remove the first two digits and return 765. Introduction ¶. A function is often used to determain which “part of a variable” to set. Asterisk will perform each action, in sequence, when that extension number is dialed. The documentation for using regex in dialplan is here: voip-info. 2 introduced the goto control statement which conflicts with the Asterisk goto dialplan application. cfg The CALLERID (num) function is one of those new functions which will replace the old applications. It defines how calls flow into and out of the system. 0. Table 21. New in 20. Any audio generated by the hook gets injected into the call for the channel PERIODIC_HOOK () was set on. 1 and 4. The Verbose and NoOp Applications. Check out the old syntax of the ResponseTimeout application here. BUILD_USER - The string representing the user's name whose account was used to configure Asterisk, is returned. conf file usually resides in the /etc/asterisk/ directory, but its location may vary depending on how you installed Asterisk. The Read Application. In Asterisk 1. Unlike Playback (), however, when the caller presses a key (or series of keys) on her telephone keypad, it interrupts the playback and goes to the extension that corresponds with the While somewhat simple and primitive, it’s a good example for learning about conditional branching within the Asterisk dialplan. The syntax for an extension is: 1. 1. Dialplan Basics. Here we make an admin/marked user out of the 'my_user' profile that you define in confbridge. 2 - BILLING. u - Retrieves the raw, unprocessed value. (see SectionName below) sequence - CDR sequence number. In this tutorial we will show you its syntax and possible usage. Test Suite Documentation. Chapter 6. Dialplan Functions ; Module Configuration ; Example: Play an MP3 playlist This documentation was generated from Asterisk branch 20 using version GIT . Thus the following dialplan would not be equivalent: exten => 1000,Set(sip_codec=g729) same => n,Dial(SIP/1000,15) This can lead to some rather confusing situations. An extension is simply a named set of actions. pro-sip*CLI> core show function CURLOPT. Example: Usage on pre-connect handler. exten => s,1,Set(foo=${VMCOUNT(125@default)}) An ampersand-separated list of mailboxes may be specified to count voicemails in multiple mailboxes. Example¶ The following example shows one way of accessing the channels that have hangup cause related information after a Dial has completed. Let’s assume for the sake of this example that the victim’s phone number is 888-555-1212: Some of the contents of a CEL event are user-defined. For example, a dialplan function might retrieve the Caller ID information from an incoming call SIP_CODEC is set in the dialplan, but it gets evaluated inside of Asterisk, so the evaluation is case-sensitive. CONNECTEDLINE dialplan function¶ The CONNECTEDLINE function does the opposite of the CALLERID function. Here is some example usage: Dialplan Basics. For example, a call might come into Asterisk dialplan, which might use one application to answer the call, another to play back a sound prompt from disk, and a third application to allow the caller to leave voice same => n,ConfBridge(1) This example shows how to use a predefined user profile in confbridge. Example usage of the function CUT: exten => s,1,Set(foo=${CUT(bar,,2)}) The above example sets the variable foo to the function CUT whose first parameter is ‘bar’, second parameter is empty and third parameter is ‘2’. One of the most important keys to building interactive Asterisk dialplans is the Background ()[ 75] application. ! expr1. Information about a particular function could be obtained by typing the show function <function name> on the Asterisk CLI Description. e. For example, in asterisk CLI. For a more fine-tuned jitter buffer, disable this option and use the JITTERBUFFER dialplan function on the calling channel, before it enters the ConfBridge application. Pattern matching saves us from having to create an extension in the dialplan for every possible number that might be dialed. Introduction - A Simple Audiohook. It is important to note that this takes place after variable substitution. Syntax: GoTo ( [ [context|]extension|]priority) ; the context and extension are optional settings. In other words, if expr1 is null, 0, an empty string, or the string "0", return a 1. The Geolocation capabilities are implemented in Asterisk with the res_geolocation and res_pjsip_geolocation modules and the geolocation. Check out the old syntax of the SetCallerID application here. Historical Documentation. Q. 2 or 100300 for 10. value - maximum time for response in seconds. exten => addheader,1,Set(PJSIP_HEADER(add,X-MyHeader)=myvalue) Early Media and the Progress Application. Dialplan Functions tend to be geared towards manipulating channel data and attributes as well as providing general tools All fields of the CDR record can be accessed in the Asterisk dialplan by using the CDR() function. The VOLUME function can be used to increase or decrease the 'tx' or 'rx' gain of any channel. GoTo - this application allows you to jump to another extension, another context or another priority. exten => s,1,Set(foo=${CUT(bar,,2)}); This is correct syntax. The optional skip field tells Asterisk how many digits to strip off the front of the value. Otherwise, return a 0. To demonstrate, let’s look at the following code: To save Subscriber Number, you can write an entry for OWN NUMBERS storage on SIM. Let’s look at the types of operators that are available in Asterisk: This is useful when you want certain people to be the first to answer any calls, with immediate fallback to a queue when the front line people are busy or unavailable, but you still want front line people to log in and out of that group, just like a queue. To set it to something, use the CHANNEL() dialplan function. Asterisk 20 Documentation. min defaults to '0', if not specified, while max defaults to 'RAND_MAX' (2147483647 on many systems). Like Playback (), it plays a recorded sound file. The CDR() function is also used to set the fields of the CDR that are user-defined. exten => s,2,Set(foo=${CUT(${bar},,2)}); This is invalid syntax (unless bar contains the name of amaflags - R/W the Automatic Message Accounting (AMA) flags on the channel. conf configuration file. [Synopsis] Set options for use with the CURL() function. The dialplan is the heart of your Asterisk system. SMS. From the context of executing the dialplan defined in extensions. This option makes use of the JITTERBUFFER dialplan function's default adaptive jitter buffer. When read from a channel, the integer value will always be returned. Long Running Operations (Autoservcie) Defining Extensions Dynamically ; Creating Custom Aliases for Built-in Constructs ; Re-purposing The print Function Since phone-specific config files generally have file names based on phone-specifc data, dynamic filenames in res_phoneprov can be defined with Asterisk dialplan function and variable substitution. Aug 19, 2005 · Asterisk can make use of global, shared and channel-specific variables for arguments to commands. filename. pin: integer: Sets if the user must enter a PIN before joining the conference. Syntax ¶ FILE(filename,offset,length,options,format) One of the most useful applications in an interactive Asterisk dialplan is the Background() [] application. To refer to a variable with its name (as an argument to a function that requires a variable), just write the name. From other contexts, however, it could be a problem. key - The piece of data to retrieve from the MixMonitor. . WAV' for legacy reasons. Both URI parameters and header parameters can be read and set using this function. Syntax: Set (CALLERID (all)=name <number>) List of the possible options. value - The new number, you want to set to the caller. MIXMONITOR(id,key) Arguments. API Documentation. 6. Here we'll list all of the special built-in dialplan extensions and their usage. silence - It is optional. cfg = 000000000000. It can be g723, g729, gsm, h263, ulaw, alaw, vox, wav or WAV. Some example extensions. Like Playback(), it plays a recorded sound file. Consider that a user wrote the following dialplan. When written to a channel, both the string format or integer value is accepted. NOTE: This application is valid for Asterisk version 1. If a folder is specified, this will apply to all Arguments. MacroExclusive. exten => 115,1,Verbose(Call start time: ${CDR(start)}) same => n,Set(CDR(userfield)=zombie pancakes) Modules. AMI Actions. GoTo (dialplan application) 1. Unlike Playback(), however, when the caller presses a key (or series of keys) on her telephone keypad, it interrupts the playback and passes the call to the extension that corresponds with the pressed di There are two reference modes - reference by value and reference by name. Choose a random number between min and max. A form of scripting language, the dialplan contains instructions that Asterisk follows in response to external triggers. AMI Events. Each variable will be on its own line, in the form: agi_ variable: value. Cut out information from a string ( varname ), based upon a named delimiter. 1, “AGI environment variables” will be the first pieces of information sent from Asterisk to your application. Asterisk 21 Documentation. If 'live_dangerously' in 'asterisk. Record - this application allows you to record a voice. Syntax: Set (CALLERID (num)=value) List of the possible options. HOOK_CHANNEL is the channel the hook is enabled on. 1+ has full support for it. Simple Audio Hook ExampleL In this simple example, a SIP phone has dialed into Asterisk and its channel has invoked a function (pitch_shift) which has been set to cause all audio sent and received to have its pitch shifted higher (i. SIG is an example where the caller name may be delayed so your dialplan may need to wait for it. Note. lua file. For example, the userfield is user-defined and will be empty by default. Example: Example 2. Here is an example within Asterisk dialplan. URI parameters appear in the URI (inside the <> in the header) while header parameters appear afterwards. 2, they should be used where possible. 13. name - The new name, you want to set to the caller. Shared Line Appearances SLA. New in 16. conf' is set to 'no', this function can only be executed from the dialplan, and not directly from external protocols. Dialplan Function Modules. The extensions. -= Info about function 'CURLOPT' =-. Other than special extensions, there is a special context "default" that is used when either a) an extension context is deleted while an extension is in use, or b) a specific starting extension handler has not been defined Gosub syntax is simple, you only need to specify the priority, and then optionally the context and extension plus any arguments you wish to use. This will allow you to do your entire macro in a single line. This example uses the CALLERID function, which allows us to retrieve the Caller ID information on the inbound call. 3 - DOCUMENTATION. Writing to the FILE() function can change any file that Asterisk has write access to. kt tk ek gy ed fi dk lo kd nj
