Trying to change the MOH on Directory numbers. Go to update phones, add directory number. "Add to Query" under Paramiters select "User hold audio source" go to value select "source" then "Set Value" check reset devices. At this point I can view results and see my directory numbers I want to change. I click update. My phone resets.... I go to call manager admin. no change on my extension. WHAT AM I DOING WRONG? it will not make the change. I have 1,400 device I would like to change.
