Help with Spying on a Conference

I wish to be able to spy on a conference. My solution is simply to join a bridge with mute enabled and no announcement. The problem of course is when I do this it kills the Music the person is listening to if only one participant is in the conference thus giving myself away.

Any solution to this?

There is no capacity to spy explicitly on a conference. You can only spy on channels, so you either have to create one or spy on an existing one.
