i have an M3904 set on my desk and an M2616 in my switchroom. My PDN on the M3904 is also programmed as an appearance on the switchroom phone. I set the CLS to POD because whenever I am in the switchroom and my manager is near my regular desk and my phone rings he answers it and listens to my conversation without my knowing it. SO i am fairly certain that making both phones POD will eliminate that. But, I actually don't want him to answer my M3904 set AT ALL. Can I lock it somehow?
