how to programmatically launch the New Call dialog of NetMeeting

Hello,
I'm programming a Java application. 
Now, I'm wanting to integrate the video conference function into the
application. I intend to launch the "place a call" dialog of
NetMeeting in the application, maybe through calling complied dll file
using com interface.
does any one have good ideas?

I look into Netmeeting SDK, but does not find any resolution.

Thanks.
