What am I missing?

Probably establishing the connection on the device won't be sufficient as windows will not be notified of the connection. You should setup a modem in Windows and use this to establish the connection.

DotRas ist a project to do exactly this in c#. But there may be other solutions for other languages as well. If you are scripting you can have a look at WMI. There are classes for modems as well.
