This step is mandatory. It appears only if you chose at the start of the task to remove subscriber lines associated with the hardware you are removing, and removing these lines has left one or more Business Groups or PBXs with no Business Group Lines or PBX Lines configured.
The Details panel shows all the Business Groups and PBXs associated with the hardware you are removing that now have no associated lines, and displays information about their current status.
Click on Confirm to confirm removing these Business Groups and PBXs.
