        My response would be to demand instant refunds and 
        adjustments when each and every bill is received, quoting 
        their own sales literature, web sites, whatever.

        I would also test the heck out of the situation, trying
        all possible permutations.

        As far as testing goes:

                a)  What happens when an analog modem is used
                    on the "phone line" of the ISDN line?

                        a1)  What happens when calling a random
                             number (another user who can set up
                             his modem to "answer")?

                        a2)  What happens when the customer is
                             calling one of your PRIs?

                b)  What happens when a fax machine is used
                    on the "phone line" of the ISDN line?

                        b1) See (a1) and (a2) above.  Even though
                            it will not "work" when calling you
                            PRIs, try the same thing, just to log
                            a call.

                c)  What happens when the ISDN modem in question
                    places a DOV call to another number (perhaps
                    that of a another ISDN user)?  Perhaps the
                    "special equipment" is a simple correlation
                    between (ISP) PRIs known to GTE and the called
                    number.  Such a "billing  hack" might be the
                    sole "special equipment" used to "detect"
                    such calls.

                d)  What happens when a 2 minute call is placed
                    using DOV?  What happens when a 30 second call
                    is placed using DOV?

                e)  What happens when placing a DOV call to an
                    out-of-area PRI, not within the service area
                    of the telco in question?

                f)  If GTE is in the ISP business themselves,
                    what happens when the user calls THEIR
                    PRI?  Do they even support DOV?

                g)  What happens if the user uses his phone
                    to place an ISDN voice call to your PRI?
                    
                All of the above questions require a notebook and
                careful attention to the time each call was placed,
                since one wants to compare actions to bills.  The 
                bad news is that the test results will take a month
                to come back.

        The holy grail of "catching" people who use DOV has been
        the subject of much discussion within all the telcos.  I know,
        because our main revenues are gained from the sale of massive
        databases that track and control central office equipment, 
        provisioning and so on.  If there were such equipment, it would 
        be big news.  To my knowledge, there is no such equipment.  If
        ANY of the major telcos heard even a whisper of such equipment,
        a request would be made to add a new data table to the database
        schemas to track, control, and assign such equipment.

        If the "catching" were done at the switch level, the software
        build (from AT&T, NT, whoever) would be clearly documented
        to describe the "enhanced feature".  No such doc has crossed
        our desks, and we keep a very complete set of 3-ring-binders.

        Therefore, I suspect either:

                a)  The Northern Telecom DMS100 "bug" mentioned
                    earlier in this thread.

                b)  A billing hack, where calls made to specific
                    numbers (known ISPs) are flagged as data calls
                    based upon dialed number data.

        If GTE is doing a "billing hack", AND if GTE is also in the ISP
        business, I would offer the opinion that the next step would be
        formal complaint to both the FTC and the local utility regulators 
        on one or more of the following grounds:

                -  Deceptive sales practices to end-users
                   regarding the definition of a "voice" call,
                   and the actual billing versus the definition.

                -  Restraint of trade (against [other] ISPs)

                -  Violation of published tariff (the call is
                   clearly a voice-type call)

                -  RICO  (since there is clearly a pattern of
                          ongoing criminal activity)

        This could be a fun little battle if you are willing to test 
        all possible variations to expose any possible connection
        between the "Called Number" and the (ahem) "special equipment".


  We are not so poor to be forced to trash Earth, nor rich enough to afford to.
