Disable music on hold for parked calls only?

Hey everyone is this possible? I want to have hold music but for parked calls I want it to be silent. This way if I’m on a conference call at my desk and want to move to the conference room, I can park the call and pick it up there. Right now I can’t because it plays hold music to everyone on the call! It doesn’t seem to show any option under parked calls for hold music, so I assume it’s just using the default hold music. Any ideas?

Been a while since you posted this, but why not just upload an “empty” sound file and create a playlist from that?
