I thought the same thing at first, but then started wondering about a
man-in-the-middle attack.  

Supposed asterisk simply used the Motorola ATA as a "dongle" and
forwarded any tough authentication questions to the ATA and forwarded
the ATA's answers back to the remote SIP server?  Could that be made
to work?
