INTRODUCTION:  So, you want to phreak from a pay phone, but you are in a bad 
situation.  You need to make a call, yet you do not have an 800 extender or 
or 950 extender.  And of course you have no quarter (or are too cheap to 
spend one).  And to top it all off you don't have any sort of "box" or tone 
generator.  So, what will you do?  Well, by reading this file on basic ways 
to manipulate (aka: social engineering) various parts of the phone network 
you will be able to make that call.  This file is broken down in to a few 
parts.  They are: 
 
       I.  Charging the call to a OCC (Such as MCI, Sprint, etc.). 
           A.  Charge and then use a PIN. 
           B.  Third party charge (no PIN needed). 
       II. Charging the call to a BBS. 
           A.  Call and Connect to BBS. 
           B.  Third party charge. 
 
PART I:  In order to accomplish this method you must first have the dial-up 
extender number for an OCC (Other Common Carrier).  Any OCC will do.  I have 
found that MCI works well (but that is more preference than anything else). 
 
    A.  In this method you will be charging a call to the OCC.  When the 
        operator part of the call is complete then you will dial in the PIN 
        you have, plus the other numbers in that particular OCC format to 
        place the call.  For demonstration I will use the local MCI at my 
        disposal. 
 
        1. First, call up the OCC from the pay phone as if you were going 
           to make a collect call (0+pre+suff). 
        2. When the operator answers tell them that you would like to charge 
           the call to the number dialed.  When they ask who is calling 
           give them any name.  It would help if you refrained from using 
           your last name for obvious reasons. 
        3. Now it can get a bit tricky.  In order to accomplish this next 
           part you must change your voice to sound like someone else.  And, 
           it must be convincing.  When the OCC answer with that drab yet 
           perky tone quickly press the first # in the format needed to make 
           a call through that OCC.  Once this is pressed the tone should 
           stop.  Some OCCs allow you to press a # or * without it being 
           part of the PIN, some do not. 
        4. Now, doing the best acting job you can politely answer (in your 
           different voice) "HELLO?"  In case you are lost, you are 
           impersonating the person you have supposedly called. 
        5. If your acting job is good the operator will ask you "WILL YOU 
           ACCEPT A COLLECT CALL FROM [your name]?" 
        6. In your acting voice simply answer "YES" 
        7. The operator will hang up.  You should hear a click as he or she 
           hangs up.  Once the operator is gone continue with the rest of the 
           numbers needed to finish the sequence. 
 
        HINTS/NOTES:  This method must be done quick.  If you delay too long 
                      then you might time out on the OCC and have to start 
                      over again. 
 
    B. In this method you do not have a PIN for the OCC you are charging to. 
       Thus, you will do a third party billing to accomplish your mission. 
       Again, I will demonstrate on my local MCI system. 
 
       1. Dial the number you wish to call in the collect call format 
          (0+NPA+PRE+SUFF). 
       2. When the operator cuts in tell him/her that you wish to bill this 
          call to another number.  They will ask the number.  Give them the 
          OCC extender you are going to use.  As in the above process, when 
          they ask for your name give them any old name. 
       3. Once again you must slip in to your alternate personality in order 
          to fool the stupid operator.  When the operator calls the OCC number 
          to verify your charging it to them answer by pressing any number to 
          shut off the tone.  The simply say in your acting voice "HELLO?" 
       4. The operator will ask you if you will accept a third party billing 
          from the real you.  You simply answer "YES" 
       5. Since your charging the call is approved the operator will now 
          connect you to the number you really wish to call and thank you 
          in a very friendly tone for using their service.  They are so 
          nice and helpful. 
 
       HINTS/NOTES: In this form speed is not a critical issue.  But remember 
                    to stay calm. 
 
PART II:  In order to pull this form off you must be a VERY good actor and 
sometimes a bit lucky.  You will need the number of a BBS or any line that 
produces a carrier tone.  It would not be nice to charge to one of your 
favorite boards.  I recommend the local 13 year old supEr ElitE piratE board. 
These boards usually work great. 
 
    A. In this method you are going to charge and connect to the BBS.  This 
       works well for hacking a system, or logging on to a board you really 
       do not care for.  But, you must have a portable or a laptop to 
       accomplish this method.  You must also have good knowledge of your 
       little system so that you can connect before the carrier tone drops. 
 
       1. Call the BBS as if you were charging the call (0+NPA+PRE+SUFF). 
       2. Tell the cheerful operator that you wish to charge the call to the 
          number dialed.  And once again, give the operator any old name. 
       3. When the BBS answer the phone use you by-now-perfected actor voice 
          to answer something like "HELLO?  DAMN MODEM, I CAN'T SHUT IT OFF" 
          talk loud, otherwise the operator might not here you over the tone. 
       4. When asked if you will accept charges yell "YES!" 
       5. When the operator clicks off have you laptop modem pick up and 
          bingo.  Instant connect. 
 
       HINTS/NOTES: This form can be trouble sometimes.  It is also not very 
                    practical.  But hey, it works. 
 
    B. This method is much like PART I, SECTION B.  The only difference is that 
       the third party billed to is a BBS, not an OCC.  Simply follow those 
       instructions plus ITEM 3, from PART II, SECTION A and you will have 
       no problems. 
 
       HINTS/NOTES: Just like SECTION A of this part it can be trouble 
                    sometimes.  And that damn carrier tone has been known to 
                    induce headaches at times. 
 
CONCLUSION:  Well, I know that this covers the bare basics of pay phone 
phreaking.  Like I said before, it is used when you have absolutely no 
resources or are too cheap to use them.  There are, however, a few more notes 
that you should be aware of.  They are: 
 
        1.  Occasionally you will get an operator who knows what you are trying 
            to do.  I suggest you hang up and find another phone to try it 
            from.  I personally have had the operator send a AT&T Truck out to 
            investigate. 
        2.  Some OCC numbers will be listed as numbers that cannot accept 
            collect calls.  This usually happens because you have, or someone 
            else has, charged a call or calls to it before.  In my experience 
            they have only flagged the roll-over line.  That is, the main line 
            you call.  Set up a scanner to search out the actual lines you are
            rolled over to.  I personally have a list of 50 lines that my local 
            MCI uses.  When one gets flagged for charged calls, switch to 
            another. 
        3.  I have used these methods to charge Alliance Teleconferences 
            before, as well as go overseas. 
        4.  Like I have said many times, these are basic ways to accomplish
            your mission.  I am currently working on "Advanced Ways to
            Accomplish Other More Interesting Missions"  All of this "mission"
            talk makes it seem like you are actually the conspirator trying to
            ruin the US like the secret service tries to make us look.  Heh.
 
 
Please excuse all typos and spelling errors.  And remember, let's be careful
