But you _can_ use SetGroup/CheckGroup/GetGroupCount if you don't put the 
SIP peer directly into the queue, but instead add a Local/.. channel 
that makes the Queue call out to the agent via a special context in your 
dialplan. This special context can then do anything it wants, including 
returning Busy/Congestion back to the Queue app if needed.
