Automatic forward a call

I know that WP has a way to forward a call but I would like to build a app to manage that. So I have tried to check what APIs are available for the phone functions but I don't seem to find one regarding call forwarding?

So any help in pointing me in the right directions are appreciated!

Solution

There are no APIs available to do this. (As far as I know not even the operator-only ones can pull this off.)
