PHP AGI ( Asterisk Gateway Interface ) facade, with CDR ( Call Detail Record ), Call spool and schedule auto dial, Send and Receive Fax, Channel Variables, and Caller ID management

README.md

Introduction

This framework is intended to simply making ivr applications using Asterisk's AGI, providing a nice level of abstraction over what an IVR should look like from a developers' perspective.

Included Example

Please see docs/examples for all the included examples.

You can start by docs/examples/quickstart for a very basic example. You'll need something like this in your dialplan:

[default]
exten => 1,1,AGI(/path/to/PAGI/docs/examples/quickstart/run.sh,a,b,c,d)
exten => 1,n,Hangup

Available via Composer

Just add the package "marcelog/pagi":

{
    "require": {
        "marcelog/pagi": "dev-master"
    },
    "repositories": [
    {
      "type": "pear",
      "url": "http://pear.apache.org/log4php/"
    }]
}

Packagist URL: (http://packagist.org/packages/marcelog/pagi)

Available via PEAR

You can now easily install PAGI by issuing:

pear channel-discover pear.marcelog.name
pear install marcelog/PAGI

or

pear install marcelog/PAGI-X.Y.Z

just replace X.Y.Z by the release version you'd like to install :)

See the pear channel

Available as PHAR

Just go to the Jenkins server and grab the latest phar distribution from the PAGI job.

Testing IVR applications

A mocked pagi client is included to easily test your ivr applications. See docs/examples/mock to see an example of how to use it.

Nodes

For a tutorial about nodes, see this article

Simple Call Flow Nodes are available (see docs/examples/node/example.php). Using nodes will let you simplify how you build and test your ivr applications. Nodes are an abstraction layer above the pagi client, and support:

  • Prompts mixing sound files, playing numbers/digits/datetime's.
  • Cancel and End Of Input digits.
  • Validator callbacks for inputs, can optionally specify 1 or more sound files to play when the validation fails.
  • Callbacks for invalid and valid inputs.
  • Optional sound when no input.
  • Maximum valid input attempts.
  • Optional sound when maximum attempts has been reached.
  • Expecting at least/at most/exactly N digits per input.
  • Timeout between digits in more-than-1 digit inputs.
  • Timeout per input attempt.
  • Retry Attempts for valid inputs.
  • And much more!

The NodeController will let you control the call flow of your application, by registering nodes and actions based on node results. Thus, you can jump from one node to the other on cancel or complete inputs, hangup the call, execute a callback, etc. For an example, see docs/examples/nodecontroller/example.php

An article about the node controller is available here

AutoDial

CallFiles are supported. You can also schedule a call in the future.

Fax

Sending and receiving faxes is supported using spandsp (applications SendFax and ReceiveFax).

Available Facades

  • PAGI\Client\CDR: Provided to access cdr variables.
  • PAGI\Client\ChannelVariables: Provided to access channel variables and asterisk environment variables.
  • PAGI\Client\CallerID: Provided to access caller id variables.
  • PAGI\Client\Result: Provided to wrap up the result for agi commands.
  • PAGI\CallSpool\CallFile: Call file facade.
  • PAGI\CallSpool\CallSpool: Call spool facade.
  • PAGI\Logger\Asterisk: Provides access to asterisk logger (see logger.conf in your asterisk installation).

Results

For every operation, a Result is provided. Some operations decorate this Result to add functionality, like PlayResult, ReadResult, etc. For example, a stream file will return a PlayResult, which decorates a ReadResult which in turn, decorated a Result.

  • PAGI\Client\DialResult
  • PAGI\Client\ExecResult
  • PAGI\Client\ReadResult
  • PAGI\Client\PlayResult
  • PAGI\Client\FaxResult

Debugging, logging

You need log4php. Just make sure you copy it to the include_path and PAGI will pick it up from there (the directory src/main/php is the one that needs to be in the include_path).

Developers

  • build.xml is a phing build file, not ant.
  • It's very possible that you may need to edit build.properties.
  • Available main targets: all, build, test, report.
  • Tools run: phpdoc, phploc, phpcs, phpmd, phpcpd, phpdepend, phpunit.
  • Setup your installation by editing pear and php paths in build.properties
  • Run phing install-dependencies this will install pear and everything needed to run phing tests and metrics.
  • Copy resources/php.ini.example to resources/php.ini and edit it.
  • Run phing all
