I browsed around the site for a good 20 minutes but could not tell whether asterisk is an application platform that I can build various voice apps on top of. Say I wanted to build an app that when I click a link on my website, it sends a message to the * box, * then dials your cell phone (preregistered on your pc) and calls the number displayed on the link and puts them together. So this is an example. Can I do stuff like this? If so is there a language manual?
