Start by using the search box found on the left, and search for topics such as:
SIP
Channels

Step 1 : Choose a Frame Work
um.... not too many options unfortunately
Once you have wrapped your mind around the various VoIP features, terminology and technologies, you will want to choose a platform or framework on which to develop your AGI scripts.
The most widely used, though utterly "obese", framework is the OpenSource project PHP-AGI. This is hosted by SourceForge and makes use of OOP techniques to access Asterisk functionality.
However, if you wish for more control, you might consider writing your own mini-framework, as I did. You can have a look at my single-file function library for PHP I wrote here:
PHP AGI Function Library by Ralfe Poisson.
