[dba-VB] Making A Phone Call From A Visual Basic Application

To all,
 
We are operating a windows 2000 network with windows XP desktops and as per usual we connect to the internet through our network.  I’m trying to look a bit further into the future of our internal application, we have a Visual Basic FE connected to a SQL Server 7.0 BE.  On this we have personnel and client data, what I want to be able to do is have a button next to the phone number so that when the user clicks it, it dials the number for them.  I don’t think I can get into our phone network, but is there a way I can connect a headset to the PC and dial the number through our internet connection ?
 
I hope I’ve explained what I want to do clearly enough, any help, pointers in the right direction etc will be greatly appreciated.
 
Thanks in advance.
