There was a discussion last year in either net.dcom or fa.telecom on
methods of beaking into dialback (without physical access.)  They mostly
related to the window in which an incoming call may be received by the
line being used for dialback.  If the cracker then plays a dial-tone,
the dialback site can be convinced that it has reached its intended number.
