Is there any way to cause the system to refuse to park a call at any given shared park location if that location already has a call parked there? If the same person parks 2 calls at the same SP location I don't see any way to answer a specific parked call. It would be helpful if the MyPhone app would use an unused SP location when parking a call. As it is, it always uses location 0 even if there is already a call parked there. Or am I missing something? Is it poosible to setup additional Shared Park extensions so that everyone could have their own? This would help.
