Override the default outgoing call screen.

Hi,

I'm trying to override the default outgoing dialer application, and replace it with my activity. I've already got my receiver working and responding properly when an outgoing call is made, but I can't figure out how to prevent the default dialer from displaying and replace it with my custom layout.

When I switch back to my custom application, I can see that it has loaded my dialer layout. It does not take the place of or display on top of the default dialer. Any ideas?

Any ideas?
