  Hmmm... off-shore 900 number?  Or maybe an 800 
number of a business he doesn't like.  Imagine the
phone bill an 800# would rack up if it were to be
called by thousands of random computers.

  Nope.  ISP's don't log every single packet that 
goes through their machines.  Depending on the size
of the ISP, the logs would easily be in the gigabytes
or even terabytes each day.

  If they essentially shrug their shoulders about Code 
Red II, which installs a back door on every computer 
it infects, do you think they really care about an 
isolated incident of your modem hanging up and dialing 
out?

  IIRC, there's a command you can put in your 
initialization string to prevent that from happening...
Yes, there it is, "To protect yourself you can disable 
the +++ command by setting the S2 register to 255"
