I have just completed creating a WEB based calling system. It is broken into three different sections.

Point to Point

This allows the ability to type in a source and destination phone number and the 2 calls are then connected together.

The main advantage to this is that it has powerful routing and resume functions. The functionality is base on the section Callback Advanced Call Routing

Prerequisite

For the above to work you must have Apache and PHP installed. Usually this is done when installing Linux. You also have to change the permissions of an Asterisk folder so that Apache can write a file so Asterisk can initiate calls. 

chmod 757 /var/spool/asterisk/outgoing
