Winsock control for asp.net

Hi,

one of our old project written in VB6 uses winsock control to receive events from the server.
It is a telecommunication server, when the call is coming it throws a event, my VB application catch that event and react based on that. like when ever the event(call,disconnect,hold..) occurs in the server it throws event.and the app catches that events,

In winsock it has start,stop,data_arrival..etc events.

I want to implement the same functionality in my asp.net c# applications. is there any control is there to keep on getting the event from the server?

kindly give your valuable suggestions.
