Hi, I’m new to asterisk!

We want to add a new functionality to a HelpDesk software tha we a are developping. We want to automatically create a new case each time a customer call. Is there a way to use asterisk, or a library of it, to listen to a phone line and get the caller ID?

Thank you,  
Nicolas B

You would want to use the Asterisk [AGI](http://www.voip-info.org/tiki-index.php?page=Asterisk+AGI) to develop an application external to Asterisk to do this. A couple of libraries to give consideration depending on your langauage of choice:

- [Java](http://www.asteriskjava.org/)
- [PHP](http://phpagi.sourceforge.net)
- [.NET](http://www.gotdotnet.com/codegallery/codegallery.aspx?id=7948963b-7a3b-4303-9118-da800f4f84c3)
