IVR Setup - Enable Direct Dial (limit to Directory context)

Hi

I am missing something

I am trying the above code, and nothing seems to happen.

Exactly where do I find the IVR Directory Context and/or how do I setup the the approved extension per IVR

I am trying to limit dialed extensions per IVR - so that cross over is eliminated
and only approved extensions can be dialed by the calling party.

Thanks
