OVERVIEW
--------

Include it:

require 'phpagi.php';

Construct it:

$agi = new AGI();

This creates a new AGI object with all the agi vars read in, you're now ready
to rock and roll.

Answer the line.

$agi->answer();

Play a file.

$agi->stream_file('somefile.gsm');

Record a file.

$agi->record_file($file, $format, $escape_digits='', $timeout=-1, $beep=false, $silence=NULL)

There's more, read the class or refer to the PHPAGI website for more information.  

                     This README is seriousley lacking.

CONFIGURATION
-------------

phpagi supports an ini style configuration file, and run time configuration.

By default the class reads in the contents of /etc/asterisk/phpagi.conf into
$this->config.  The format of the ini file is as follows:

[examplesection]
foo=bar
bar=dew
dew=pale ale

This is read into $this->config as:

$this->config['examplesection']['foo']='bar';
$this->config['examplesection']['bar]='dew';
$this->config['examplesection']['dew']='pale ale';


Run time configuration is also supported.  Pass an array of variables and values as the
second parameter to the AGI constructor, these fields are stored in $this->config['phpagi'].

ie:

$myconfig=array(
	"error_handler"="true"
);

	$agi=new AGI("/etc/asterisk/phpagi.conf",$myconfig);


The following run-time configuration options are used by the phpagi class to change behaviour.  They 
are all contained in the $this->config['phpagi'] array.

 * error_handler - set to "true" (string) to enable php debugging
 
	
EXAMPLE APPLICATION
-------------------

ping.php is an example phpagi application.  it asks for an IP address to be
entered, and reads back the results of a "ping" summary.

to use it, you'll need festival installed.  see  http://www.voip-info.org/tiki-index.php?page=Asterisk+festival+installation 
for all the groovy bits to get festival working with asterisk, then configure
phpagi to use it too:

in /etc/asterisk/phpagi.conf:

[festival]
text2wave=/usr/src/festival/bin/text2wave
tempdir=/var/lib/asterisk/sounds/tmp/
