Buy the book at amazon. See see Bug Asterisk 1. Queues are defined and configured in queues. This file is - as you are already familiar - divided into sections. Every queue goes in its own section. In our example, we are configuring a support queue in its own section, [support]. The following parameters are available to us:. Sets the music class of the queue. Defines an audio file which is played back to the agent before a call is answered.
This is so that an agent working in more than one queue will know which queue the incoming call is coming from and be able to answer appropriately. Sets the call distribution strategy, i. Ring the agent who has taken the least number of calls in this queue. Round-robin with memory. Begins the round-robin starting with the agent who is next in-line after the last call.
Agents with a lower penalty will always be preferred in all strategies. Sets the service level threshold; i. This is only really useful for statistical analysis for example, in asking the question "How many calls were answered within the service level threshold of x seconds?

If set, this is the context we pass the caller to if she presses a single digit while waiting in the queue. This digit is treated as an extension and the call is taken out of the queue and routed to the extension in that context.
Sets the maximum time a telephone may ring before we treat it as unattended. Sets the interval in seconds before we ring all the agents again. The relative importance of the queue compared to other queues. If an agent is a member of multiple queues, calls from higher-weight queues are connected first. For example, you might give an emergency queue higher weight. The time interval after an agent has finished a call before the system will pass another call to the agent default: 0.
Maximum number of callers allowed to be waiting in the queue default: 0 meaning unlimited. Sets how often a caller will hear an announcement indicating her position in the queue or the estimated wait time 0 turns this completely off. Sets whether the estimated wait time will be announced after the queue position. Possible values are yesno or once. Rounding level for wait-time announcements. If 0, only minutes, not seconds, are announced; other possible values are 0, 1, 5, 10, 15, 20 and Announcement sound files.
The following parameters define which sound files are used for which announcement types. Sets the interval, in seconds, for periodic announcements periodic-announcee. Please continue to hold". When set, recording as with the Monitor application is turned on and the recording format defined.
If not defined, recording is off. You may specify gsmwav caution: huge files!The dialplan is truly the heart of any Asterisk system, as it defines how Asterisk handles inbound and outbound calls. In a nutshell, it consists of a list of instructions or steps that Asterisk will follow. To successfully set up your own Asterisk system, you will need to understand the dialplan. This chapter explains how dialplans work in a step-by-step manner and teaches the skills necessary to create your own.
Please also note that this chapter is by no means an exhaustive survey of all the possible things dialplans can do; our aim is to cover just the fundamentals.
The Asterisk dialplan is specified in the configuration file named extensions. The extensions. The dialplan is made up of four main concepts: contexts, extensions, priorities, and applications. After explaining the role each of these elements plays in the dialplan, we will step you though the process of creating a basic, functioning dialplan. If you installed the sample configuration files when you installed Asterisk, you will most likely have an existing extensions.
Instead of starting with the sample file, we suggest that you build your extensions. This will be very beneficial, as it will give you a better understanding of dialplan concepts and fundamentals.
That being said, the sample extensions. We suggest you rename the sample file to something like extensions. That way, you can refer to it in the future. Dialplans are broken into sections called contexts.
Contexts are named groups of extensions, which serve several purposes. Contexts keep different parts of the dialplan from interacting with one another. An extension that is defined in one context is completely isolated from extensions in any other context, unless interaction is specifically allowed.
Contexts are denoted by placing the name of the context inside square brackets [ ]. The name can be made up of the letters A through Z upper- and lowercasethe numbers 0 through 9, and the hyphen and underscore. Context names have a maximum length of 79 characters 80 characters —1 terminating null.Explore other articles and discussions on this topic. Skip to Main Content Digium Support default.

How to use an Asterisk Callfile Asterisk call files are structured files which that tell asterisk how to initiate a call when when moved to the appropriate directory. Default is 0. Default is 5 min. Default is Account : Set the account code to use. Examples playback.
Note: it's not recommended to copy the file to the spool directory because asterisk could start reading the file before the operating system stop writing it causing a failure.

Answer dialplan application 1. Answer - this application allows you to answer the channel if there is a call NOTE: This application is valid for Asterisk version 1. Syntax: Answer ; there are no arguments for this application. Purpose and usage The purpose and the usage of this application is only one.
To answer the channel if a call is placed on it. We will give you a short example. To see how the application works we recommend to use our IAX softphone Idefisk.
You can download it from here. Please also read our tutorial to learn how to configure it to work with Asterisk PBX. Of course you can use it and for other things. We need three registered users in iax. This is because we are going to use the IAX2 protocol. So, we have registered the users anatoliyuser1 and user2. If somebody dials the first thing to be executed is exactly the Answer application.
Then we have the application Wait which will cause the program to wait for 5 seconds and then to go to the next extension according to the priority. This extension is the one with the SendText application. A message will appear on the screen.
In our case it is: This is a test for Answer application. Now, if somebody dials again the first executed application will be Answer. Then the caller will hear a playtone for busy condition. We achieve this with two extensions.
The first one contains the Playtones application and the second one the Busy application. It is very important to use the two applications together. There are applications which have a built-in Answer. Such application is Playback. By default it answers the line unless it is not set a specific option not to do so. An alternative of Playback is the Background applications. It also answers the line by default.Back to Tutorials.
Wait dialplan application 1. Wait - this application allows you to set a period of time to be waited, before something else to be executed NOTE: This application is valid for Asterisk version 1. Syntax: Wait seconds ; write as argument the period of time you want to be waited.
Purpose and usage You could use this application for different purposes but its usage is very simple and it does only one thing. It waits for a definite period of time before something else to be executed.
Below, we will give you an example. To see how the application works we recommend to use our IAX softphone Idefisk. You can download it from here. Please also read our tutorial to learn how to configure it to work with Asterisk PBX.
Of course you can use it and for other things. We need three registered users in iax. This is because we are going to use the IAX2 protocol. So, we have registered the users anatoliyuser1 and user2.

On the picture above you can see a screenshot of our extensions. We have two separate lines and When somebody dialsthe system will answer the call. The next step is the execution of the Wait application. The Asterisk PBX will wait 10 seconds we have set 10 as argument in the brackets before to go to the extension with the next priority.
The purpose of this extension is to play a welcome message. We will use the application Playback. So, the caller will hear a welcome message. You can do the same with the application Background. The difference between Playback and Background is that if you use the first one, you have to wait till the end of the message and then you can choose another option.
When somebody dialsagain the system will answer the call. The next step will be to wait for 10 seconds this is the period of time we have set as argument in the brackets. The next extension will send message to the display of the caller. In our case this message is The line will be hanged up after 5 seconds.There are few situation in call center applications where we want to transfer the call to Agent only if the real person answers the call, This logic is called Live Person Detection.

The Answer application takes a delay in milliseconds as its first parameter. Adding a short delay is often useful for ensuring that the remote endpoing has time to begin processing audio before you play a sound prompt. Otherwise, you may not hear the very beginning of the prompt. When you're first learning your way around the Asterisk dialplan, it may be a bit confusing knowing when to use the Answer application, and when not to. If Asterisk is simply going to pass the call off to another device using the Dial application, you probably don't want to call the answer the call first.
If, on the other hand, you want Asterisk to play sound prompts or gather input from the caller, it's probably a good idea to call the Answer application before doing anything else. The first parameter to the dialplan application is the filename of the sound prompt you wish to play, without a file extension.
If the channel has not already been answered, Playback will answer the call before playing back the sound prompt, unless you pass noanswer as the second parameter. To avoid the first few milliseconds of a prompt from being cut off you can play a second of silence. For example, if the prompt you wanted to play was hello-world which would look like this in the dialplan:. Evaluate Confluence today.
