Filemaker integration

wondering if anyone may have insight as to how to do this. I have a Filemaker solution(CRM program). It would be really cool to be able to click on a phone number to fire a script which activates a certain extension and dials out the number.

I am not sure what method to pursue. Is this something that is API based at the individual extension?

Filemaker has the ability to post XML commands too. thanks for any help, or pointing me in the right direction!

Take a look at the Asterisk Manager Interface. It is socket based though, not XML.
