[Freeswitch-users] Popup on incoming call on FS

I am a recent adopter of FS and sorry if this has been addressed many times before. I would like the incoming call on FS pop up screen or update a page on my desktop. I need to know how this incoming call event can be captured and the Caller-id be picked up from the same. Based on the above I am assuming a notification can be sent to the webpage. Abhik
