Asterisk config

Asterisk SIP configuration is done is sip. CONF [general] ;In this section you configure your general sip parameters and the registration string which is used to register your asterisk server with ours.

Here are few sip parameters, which we will use in our general section. Here you can create your trunk through which you will throw your outgoing calls to AXvoice. You can copy paste all the above sip configuration from the start to end and replace it with your current sip configuration file.

Reload your new sip. After that you may want to check whether your asterisk server registered with the AXvoice server or not. If under "State", it shows "Not Registered" then wait for some time and issue the command again. If still it shows "Not Registered" or "Failed" then change your credentials in the "register" command in sip. In the dialplan you tell asterisk what to do with a call when it receives one. Dialplan is created in the file called extensions.

For asterisk installation read chapter 3 of the book Asterisk the future of Telephony. A fair understanding of asterisk and its configuration files. Configuring Asterisk Dialplan In the dialplan you tell asterisk what to do with a call when it receives one.Back to Tutorials. The first context in the extensions. More on this in the upcoming tutorial on the CLI commands. The CLI is the interactive asterisk shell, where you could a. If not set, Asterisk will wait for another extension to be dialed.

It is highly recommended this option to be set to yes. In context [globals] you can specify your own variables, that can be used later in extensions.

With the exception of [general] and [globals] everything else is consider as call contexts. Press 1 for steve, 2 for Any call arriving in the mainmenu context, will first go to the s extension.

The second priority in extension s, is the wait application with parameter 2, which would just wait for 2 seconds, and as a result give ringing for 2 seconds before playing the audio file "submenuopts" to the caller as defined in the 3rd priority. The 4th priority will wait for the caller to enter some digits, such as press 1 for steve, press 2 for markthe keys pressed by the caller will be the new extension.

The caller pressed 2 and the call flow will now go to the default context, extension mark, priority 2.

A minimal working configuration is the smallest set of configuration lines that allow an application to provide a predefined level of service.

We apply our algorithm to the Asterisk voice-over-IP server using a baseline of one SIP and one analog phone connection. Using the algorithm, we are able to reduce a configuration with more than eighty files and 12, lines of configuration to a simpler system containing only four files and fifty-six lines.

The algorithm finds a local minimum configuration which, in practice, is usually the smallest working configuration set. Reducing the number of lines of configuration makes teaching and training easier and also makes it easier to customize a server to provide exactly the desired functionality without introducing security flaws.

Asterisk, like many phone systems, can be customized to provide an enormous number of capabilities and functions such as voicemail, hosted conferencing, call queuing, music on hold, and call parking [2]. Asterisk provides a plug-in architecture that allows for the development of new features. This means that a programmer can easily write code that interfaces Asterisk with other applications and devices. A default installation of Asterisk enables an enormous number of applications and features.

This makes configuring Asterisk an overwhelming task, especially for a new system administrator. The size and complexity of the configuration files makes it very difficult for the administrator to fully understand which features are enabled or currently in use. This can lead to misconfiguration of the server or security issues. It also makes training or teaching asterisk management extremely difficult. In this paper, we present a minimal working Asterisk configuration for a network with one SIP channel and one Dahdi channel.

This minimal configuration lowers the barrier for entry-level users and makes it easier to discover which features Asterisk offers. It allows more detailed troubleshooting and customization of the server and allows teachers to describe the essentials of Asterisk without expanding on every feature Asterisk provides. SIP Session Initiation Protocol is an algorithm which takes care of the setup and tear-down of calls and renegotiation of any lost connections during a call.

A hard phone is a physical device attached to the telephony server. A soft phone is a software program that provides telephone functionality on a non-telephone device, such as a PC or PDA. In our research, we used both a hard phone and a soft phone. IAX is an open-source protocol used by Asterisk servers, but not supported by many other devices. It is also not standardized. For these reasons, we chose to use SIP in our research. This file implements a basic configuration for enabling SIP connections from remote hosts.

Figure 2 also provides a graphical illustration of a SIP connection. A call is initiated by the caller, who first talks to a proxy server.

Once the callee accepts the invitation, communication takes place directly between the caller and the callee. Many SIP phones are multi-line phones which can accept multiple incoming calls at the same time. To test our SIP phones we performed the echo test application by dialing and by making calls from the phone to itself. Because SIP phones are multi-line the call will loop back from the Asterisk server and onto line two of the client.

After successfully testing the Asterisk network by performing different test calls, we began to disassemble the Asterisk software to find the minimum configuration needed to successfully run a basic Asterisk network. Figure 5 shows the algorithm that we designed to reach a fixed point of operation.

The algorithm first breaks down an Asterisk configuration file by file.After that you can enter the Asterisk CLI via following command:. Once inside you will see a lot of useful info print out for all actions on the system, Asterisk related though. You will see:. If for some reason you have some inexplicable issues, like Asterisk not being able to start, you can try to run the CLI with different set of switches which should give some application specific debug info which includes start up sequence, database connection, registration retries, etc.

If you don't need to be inside CLI, or you need just to execute some command without concern of output from CLI, you can do so by running Asterisk command with following switches being used:.

First important command s to know is the SIP debug set of commands which are useful when you need to see the SIP data stream going through Asterisk. Simple command is to enable SIP debugging for one phone with:. If for some reason the extension or trunk is not registered and the IP of the peer is not known to the asterisk, above command will not work and CLI will not show any SIP messages. In such case, if you know the IP from which traffic should come, it is better to turn on debugging for that specific IP like this:.

When you finish debugging the SIP stream, you need to turn off SIP debugging since leaving that running clutters the CLI output and you might miss other important information on the system. To turn off SIP debug run this command:. If for some reason you have issues with audio problems, some of the messages might indicate codec incompatibilities on the system. In such cases you can see the possible translation paths in Asterisk with following command:.

When you see a - sign, it means that transcoding between said codecs is not possible. In most cases, the reason for such issue is missing codec. In cases, and not limited to, where you did manual modifications to Asterisk dialplan, you need to reload the complete configuration of the Asterisk subsystem which can be done by a simple command:.

If reloading of Asterisk is not enough for the changes made, or there is other reason to do so, you can restart complete Asterisk with:. PBXware's implementation of Asterisk engine, uses AGI to control how Asterisk should route the calls, but for various reasons, you might be inclined to change few aspects of how the calls should route.

By default, Asterisk uses Dialplan to route the calls to various other places. Dialplan information is located in several conf files please check official Asterisk docs on this. When you change the dialplan in extensions. After that you will want to show the dialplan to verify that your changes have been applied to it. First command will print out a list of SIP peers on the system with additional info like online status and IP address from which they connect.

Second command will do the same but for IAX peers. Views Page Discussion View source History. Personal tools Log in. Tools What links here Related changes Special pages Printable version.

It was created in by Mark Spencerthe founder of Digiumwhich is a privately-held company based in Huntsville, Alabama. Among other things, Digium is specialized in developing hardware for use with Asterisk. As a result, Asterisk may not be vendor-independent, but it is still the most popular open source PBX. The development of Asterisk was significant, because it marked the first time that organizations and individuals could set up their own PBX without losing an arm and a leg.

Instead, the cost of an Asterisk PBX need only consist of the hardware that it runs on and the phones that connect to it; all of which are standardized, readily available and thus affordable. Like any PBX, Asterisk is basically a router for incoming and outgoing telephone calls. It can be configured to support a range of external connections using various media and protocols, as well as a large number of endpoints: usually telephones that connect to Asterisk via the network or the Internet using one protocol or another.

The operating system comes with Asterisk 1. Actually, Debian supplies two Zaptel packages: zaptel and zaptel-sourcewith a zaptel-modules package that must be compiled from the latter.

Asterisk Voicemail Configuration on Ubuntu Linux

The installation and configuration procedures below assume that a minimal Debian lenny system is already up and running, that a SIP-capable phone is available, possibly through the use of a SIP adapter, and that an external SIP account is available through a commercial VoIP provider. Assuming that nothing beyond a basic system exists at this point, a total of 75 packages will be installed as a result, including 72 dependencies:.

This produces a basic Asterisk installation. However, there is one error message that appears almost at the end of the install process:. The issue of this missing module is addressed in the next step. There is no real cause for concern regarding the previous error message. Rather, it should be seen as a reminder of what to do next, which is to compile and install the Zaptel modules. Luckily, this is easily done with the module-assistant:.

The m-a command is a symlink for module-assistantwhile the a-i option is short for auto-install. Before the actual build process starts, the above command will automatically install six new packages, including three that are kernel -specific:.

The end result is that the zaptel-modules package is produced and installed, including a number of modules for the running kernel. Among these is ztdummy. This module provides the clock source that Asterisk uses as a timing mechanism, e. A quick check with lsmod will show that, actually, a total of three new modules are loaded as a result:.

In this example, the SIP protocol is used both for setting up a channel to the PSTNusing an account with a commercial VoIP provider, and for configurating a local phone for testing puposes.

How to set up Asterisk in 10 minutes

Initially, this file contains mostly comments, so rename it for now:. Start with a [general] section, the options under which will apply to all other sections in this file unless they are overridden specifically:.

Besides the above, three more additions are necessary before it will be possible to make and receive calls.Asterisk is an open source framework for building communications applications. Asterisk turns an ordinary computer into a communications server. It is used by small businesses, large businesses, call centers, carriers and government agencies, worldwide.
