Email: marcelog gmail.The dialplan is essentially a scripting language specific to Asterisk and one of the primary ways of instructing Asterisk on how to behave.

One of the most important keys to the success of asterisk as a telephony software and product. That's about it, you can find the complete list of commands here. The error code can be one of: : Operation was completed successfully. In this case, the command is 'verbose', which accepts 2 arguments: the message to log, and the log level needed in order to log the message. Notice how asterisk passes the variables from the dialplan to your application i.

It will end when asterisk sends an empty line, which marks the end of the channel variables block. When the AGI application is called from the dialplan, asterisk will fork a new process and execute that application, communicating as stated above with it through its standard input and standard output normally file descriptors 0 -zero- and 1 respectively. This context will depend on various reasons that escape the scope of this article, so I wont get into any details. When a call is received by asterisk, it will start to execute the dial plan in the configured context. This makes AGI very easy to deal with from any programming language. So you can send commands to asterisk via your stdout and receive asterisk responses through your stdin. Asterisk communicate with the applications through their standard input stdin and standard output stdout. This will tell asterisk to start an agi application when a call is made to the '1' extension.

To start your agi application you will use the AGI dialplan application from you own dialplan.ДЇor example, in extensions. Through AGIyou can read input from the user, play sound files, control the call and its flow, and pretty much everything needed to make a successfull IVR Interactive Voice Response in virtually any programming language. AGI is just a way that allows you as a software developer to easily make telephony applications that asterisk will run someway along the dialplan.
