marcelog / PAMI

PHP Asterisk Manager Interface ( AMI ) supports synchronous command ( action )/ responses and asynchronous events using the pattern observer-listener. Supports commands with responses with multiple events. Very suitable for development of operator consoles and / or asterisk / channels / peers monitoring through SOA, etc

Introduction

PAMI means PHP Asterisk Manager Interface. As its name suggests its just a set of php classes that will let you issue commands to an ami and/or receive events, using an observer-listener pattern.

The idea behind this, is to easily implement operator consoles, monitors, etc. either via SOA or ajax.

A port for nodejs is available at: http://marcelog.github.com/Nami A port for erlang is available at: https://github.com/marcelog/erlami

Resources

PHP Versions

Note: PAMI Requires PHP 5.3+. PHP versions 5.3.9 and 5.3.10 WILL NOT WORK due to a bug introduced in stream_get_line() in 5.3.9. Please use 5.3.11+ or up to 5.3.8 (see README.PHP-5.3.9-and-5.3.10).

Installing

Add this library to your Composer configuration. In composer.json:

  "require": {
    "marcelog/pami": "2.*"
  }

QuickStart

For an in-depth tutorial: http://marcelog.github.com/articles/pami_introduction_tutorial_how_to_install.html

// Make sure you include the composer autoload.
require __DIR__ . '/vendor/autoload.php';

$options = array(
    'host' => '2.3.4.5',
    'scheme' => 'tcp://',
    'port' => 9999,
    'username' => 'asd',
    'secret' => 'asd',
    'connect_timeout' => 10,
    'read_timeout' => 10
);
$client = new \PAMI\Client\Impl\ClientImpl($options);

// Registering a closure
$client->registerEventListener(function ($event) {
});

// Register a specific method of an object for event listening
$client->registerEventListener(array($listener, 'handle'));

// Register an IEventListener:
$client->registerEventListener($listener);

Using Predicates

A second (optional) argument can be used when registering the event listener: a closure that will be evaluated before calling the callback. The callback will be called only if this predicate returns true:

use PAMI\Message\Event\DialEvent;

$client->registerEventListener(
    array($listener, 'handleDialStart'),
    function ($event) {
        return $event instanceof DialEvent && $event->getSubEvent() == 'Begin';
    })
);

Example

Please see docs/examples/quickstart/example.php for a very basic example.

AsterTrace is a full application: https://github.com/marcelog/AsterTrace.

Also, you might want to look at this article: http://marcelog.github.com/articles/php_asterisk_listener_example_using_pami_and_ding.html

For an example of using asynchronous AGI with PAMI, see docs/examples/asyncagi

The march edition of Software Developer Journal features a complete article about writing telephony applications with PAMI and PAGI.

Currently Supported Events

More events will be added with time. I can only add the ones I can test for and use, so your contributions may make the difference! ;)

Unknown (not yet implemented) events will be reported as UnknownEvent, so you can still catch them. If you catch one of these, please report it!

Currently Supported Actions

Debugging, logging

You can optionally set a PSR-3 compatible logger:

$pami->setLogger($logger);

By default, the client will use the NullLogger.

Developers

This project uses phing. Current tasks include:

Running a phing task

To run a task, just do:

vendor/bin/phing build
