There currently is no easy way to prevent an infinite forwarding loop.  If you 
come up with one, then you might well earn yourself a Nobel Prize for solving 
the Halting Problem .....

The obvious bodge is to set a hard limit on depth of recursion; if an actual 
real, live person is not reached within, say, five hops then the call should go 
to  (the originally-called party's)  voicemail.
