IMO it is not too difficult to change...  Create pool of threads pool 
waiting on queue.
the main sip thread will read the sip packet from the socket and add it 
to the queue
and raise a condition variable signalling packet arrival.

The first worker thread sleeping on condition will awaken wnd will get 
the packet from the queue
and will handle it.

Thanks
