I'm trying to add a .au file to the MoH options for the UC520.

Phone Model: SPA504G When receiving an incoming call, the phone rings and the open line light flashes green. When I pick up the phone handset, the active line light turns red for a few seconds, then goes out. I don't hear anything, nor can the incoming caller hear me, until I press the active line button only after the red light has gone out after picking up the handset and waiting a few seconds. Similarly, if the phone rings and I pick up the handset and press the active line button immediately after picking up, I then need to press that same line button 2 or 3 more times to be able to speak to/hear the caller. (Only way I can visualize it is opening the line too early, then closing it, then opening it again).
