Originate a call from Asterisk using PHP and Asterisk Manager Interface
/**
* Once this scipt is executed it will connect to the local port you have assigned to
* Asterisk (default: 5038) and send an authentication request. If successfull, it will
* send a second request to originate your call.
*
* The internal SIP line $internalPhoneline will be dialed, and when picked up the
* $target phone will be dialed using your outbound calls context ($context).
*
* Of course, you can modify the commands sent to the asterisk manager interface to suit your needs.
* you can find more about the available options at:
*
* http://www.voip-info.org/wiki/view/Asterisk+manager+API
* http://www.voip-info.org/wiki/view/Asterisk+Manager+API+Action+Originate
*
* Hope this helps!
