Catch netmeeting incoming calls in a web page

Hi everyone:

I want to know if I can catch the incoming calls to netmeeting in a
web page before the message of netmeeting appears.

Now I have an ASP.NET page (but I don't mind use an html or other)
where I have put a netmeeting object. I can catch the event
ConferenceCreated, but this don't fill me 'cause the call it's now
accepted and I can't get the name of the caller.

Someone have some ideas on how can I suply the control of the
netmeeting with my code?.

Thanks
