Listen up Geeks - Tough one for you!!

I am using the InternetDial API to try and automate connections for our work colleagues.

Now, when I double click the dial up networking icon on my desktop our RAS server is configured to allow call back and so prompts for a call back number.

However, when I use InternetDial api within my VB Exe it just connects straight on in there although it appears I am using the same connection and dialing the same number.

Anyone got any ideas or is this one too tough for you!!!
