Retrieve Parked Call Problem

I have several Polycom 600s and a Hitachi wireless. I can park calls with no problems. However no one can retrieve them. When someone dials # and the parked number the phone rings busy. Eventually the parked call times out and returns to the phone that parked it. Any ideas.

have you tried calling the parked number without the #?

Yeah, I feel like a moron. I thought you had to use the pound symbol with the parked number to retrieve it. Like Duh!
