                        Somewhere in Australia
                               May 2002

     Tucked away in wooden enclaves or against cement-rendered walls flanked by bright green palmettes we find the TriTel sitting proudly upon its metallic throne. Encased within its plastic aegis, the first TriTel I layed eyes upon beseeched me to lift its Electro-dynamic handset and finger the delicate yet manipulable keypad as I would a sweet-scented woman.

     Enough with the shit, on with the show ...

     Summation - "TriTel XP1230 Handset Un-mute & Other Payphones"
     This article basically covers the method of UN-Muting a TriTel payphone handset for clear Two-Way Communication with your accomplice, or whomever has called the phone. It also contains vital information pertaining to these new payphones seen frequently throughout all major cities in Australia. They are particularly fond of Westfield Shopping Centres and have been known to congregate within a variety of other Malls and the like on numerous occasions. Recent sitings of TriTel herds have been reported in Universities throughout Sydney and strays have been spotted roaming at the occasional public venue. 
     Appendices at the end of the document contain details and various information on other exotic and rare payphones throughout Australia.

     TriTel Payphones - The Un-Mute
     I. Un-Mute Method for the XP1230

     (i) From the Caller's point-of-view: When an External party dials the number for the payphone, they will hear two rings followed by a long beep. After this beep the Caller stays connected to the payphone for a period of approximately 2 minutes.
   · Anyone attempting to use the payphone will find that they cannot dial out since there is an incoming call occupying the line. The External party at this point will hear only a hollow sound. 
   · If anyone lifts the handset at the payphone the External party (or Caller) will hear various clicks as it is being manipulated at the source and can actually listen in on the DTMF being played down the line as the End User attempts to dial numbers on the keypad (however, there several seconds of delay between when the DTMF was heard at the payphone and when they are heard by the calling party). 
   · Whilst in this mode the Caller can actually speak to the Receiving party (at the payphone) but cannot hear any replies as the handset is still muted.
   · The Calling party remains connected for 1 or 2 minutes as mentioned earlier, they will stay connected for the duration of this period even if End User's at the payphone lift the handset and attempt to hang it up or disconnect the incoming call. As with telephone lines the Calling party has precedent over the connection of the call.

     (ii) From the [Payphone] End User's point-of-view: When the external source is ringing the payphone, for the first two rings there is no indication that a call is coming through. Once the external source hears the long beep, the LCD screen at the payphone displays  "Thank You. Please Insert Money/Coins".
     · If the Receiving party (person at the payphone) lifts the handset *before* the long beep (ie. during the first two calls only heard by the Caller): then they automatically "by-pass" it.
     · If the Receiving party lifts the handset *during* the long beep: they are able to hear the Calling party if they speak loud enough over the beep, but cannot reply as the handset is still muted. Sometimes the Receiving party is cut-off when they first lift the handset, see the following point for details.
     · If the Receiving party lifts the handset *after* the long beep: they will be automatically cut out, he/she must then depress the hook-switch and lift the handset again (or press Follow-On in some cases).
     · At this point the End User at the payphone can hear everything at the other end of the line but cannot be heard by the Caller. They must dial any random 1800 (Free to Caller) number. After a short pause of 2 or 3 seconds the handset is un-muted and both parties can have a continuous conversation minus interruptions by clicks, beeps or time-delays.

     II. The Theory

     When studying the XP1230 one begins to understand how it is possible that the Un-Mute method described here actually works. As will be detailed later on in the article, there are several outstanding features that make this payphone distinctly different to that of its rival the Telstra X2 Smartphone.

     TriTel payphones work on ROA [R]eversal [O]n [A]nswer, which basically refers to the line polarity being reversed when a number is dialled thus unmuting the handset and charging the End User accordingly (Free to Caller numbers are obviously recognised as such and the payphone cannot charge you). (For further discussion on this matter See the chapter Understanding the Payphone Line).

     The payphone is an American Protel XP1230 model which has its own internal recognition software that analyses the actual number itself against the time of day & day of the week with a charging table - this is known as Self-Tariffing.

     The reason why the Un-Mute Method works is because when the End User dials the 1800 number, the payphone itself (as an individual entity and not via CLM) analyses the number that was dialled against the time of day and the charging table, within those few seconds it realises that the number is Free to Caller and this is where ROA comes into play. The line polarity is reversed, no money is taken (since it is free) and the handset is un-muted to allow the number to connect. Obviously, the number cannot connect since there is already a call occupying the line.

     III. Dispelling the Myths

     Over the past six odd months the TriTel payphone discussion has reached a climax, during that period many myths and misconceptions were distributed by pretentious neophytes and other undesirables. Provided are some brief points outlining what, in my extensive experience, are known to be fact:

    (a) TriTel XP1230 Ring-tone: this does *not* exist. I have heard of reference to some TriTel payphones in Canberra that are alleged to have a ring tone much like a "hushed" L6 Bluephone. Since there is no evidence to the contrary, the current status quo stands that when TriTel phones are rung the only external indication that there is an incoming call is a message on the LCD screen reading "Thank You - Please Insert Money".

    (b) The following payphones *cannot* call a TriTel XP1230 payphone for various reasons:

  · Telstra X1/X2 Smartphone (Siemens Elasa)
  · TriTel XP1230 (Protel)

    When one attempts to dial a TriTel from another TriTel, the line is immediately disconnected but the Calling party is charged 40 cents for the call before it drops out. X2's on the other hand are completely barred from dialling a TriTel XP1230 in some areas, but the vast majority are not barred from calling other X2 Smartphones.

    (c) TriTel payphones *cannot* accept Telstra Phonecards: this is true. Even though the XP1230 is infact quite capable of doing so, Telstra has barred access. For further discussion on this matter and consultations with the ACCC, see the link provided at the end of the "TriTel Australia - The Specs" chapter.

    (d) Yes, using Bankcards in TriTel XP1230's is perfectly acceptible, there are numerous signs on both the payphone itself and the stand indicating this.

    (e) Free To Caller number the Called Party dials to Un-mute the handset can "eavesdrop" on the conversation: this is *untrue* and was confirmed after extensive discussion with numerous phreakers on the Aust Phreaking BBS and over the phone. The XP1230 is Self-Tariffing rather than utilising Customer Loop Metering (See Understanding the Payphone Line) and is designed to analyse the number dialled against the time of day and a pricing chart. Since the number is Free to Caller (ie. 1800-xxx-xxx) the payphone is tricked into un-muting the handset, something which occurs via reversal of the line polarity when the called party lifts the handset - although in this situation the called party is the payphone itself and the handset is already off the hook. Due to the fact that the line is already occupied with a call between the external source and the called-payphone, it cannot actually connect the 1800 number the End User dialled.

   · Who: TriTel Australia is the only major alternative to Telstra for
     public payphones in Australia (see Appendices for others).
   · Evolution: Over the past two years TriTel Australia has expanded
     from operating payphones in major shopping centres throughout
     Sydney and in South Eastern Queensland, to entering the payphone
     market across Australia. They are found in Universities, shopping
     centres and a few public locations in almost every State and
   · Payphone: TriTel use an American payphone that was proven in the
     USA to be "highly vandal resistant" - the Protel XP1230.
   · Objective: Deliver real benefits to the Australian public by
     offering substantially better rates than Telstra payphones.
     Compete with Telstra's long-standing monopoly of the payphone

     For further discussions on Telstra's smartcard technology trial and its associations with TriTel paphones see "ACCC To Monitor Negotiations Over Payphone Service":


     Protel International & the TrendTek connection
     TriTel Australia makes use of the American payphone produced by Protel International, one of the major US payphone manufacturers. The payphone itself was provided through a contract with TrendTek Australia, the supplier of telecommunications products to major carriers, service providers and retail organisations throughout the Asia Pacific region. TrendTek receive the Protel XP1230 model via Galaxy Payphones (Supplier Code N1141). In addition to supplying TriTel with their payphones, TrendTek supplies various products to organisations such as Telstra, Optus, Alcatel, AT&T Australia, Ericsson, Australia Post and Queensland Payphones.

     The particular model utilised by TriTel is titled the Protel XP1230 and supports a variety of payment methods and access network connections. Network connection of the various payphones TrendTek offers can be provided via:

   · Conventional PSTN copper links
   · Cellular Wireless Networks (GSM, CDMA, AMPS)
   · VHF/UHF radio links
   · Digital Pair Gain systems

     Beneath the vast majority of these payphones - just under the cash box to be precise - is a sticker with the following details: "Galaxy Payphones (Supplier Code N1141) TrendTek Australia".

     Understanding the Payphone Line
     I. Payphone Lines

     Standard payphone lines differ in several ways to that of a normal telephone line. In this section I will attempt to outline the main features which distinguish its line configuration.

     (1) Dial Tones: Payphone lines have a 60-second dial tone; as opposed to normal lines which have a standard 10 seconds (allowing customers time to insert money and dial).
     (2) ROA (Reversal On Answer): refers to the reversal of line polarity when the called party lifts the handset. This is necessary to indicate to the payphone when it should take the money, un-mute the handset and allow two-way conversation.

     (3) CLM (Customer Loop Metering): refers to a mechanism for charging calls to mobile phones, long distance and so on. For each timed period the exchange sends a pulse which is used to signal the payphone to deduct another 40 cents (1 meter pulse = 1 local call). Telstra payphones require these meter pulses to operate - this includes their Customer Operated L6 Bluephones and C4 Goldphones.
     (4) Self-Tariffing: the [Protel] XP1230 TriTel payphone does not utilise CLM to operate. Instead, it is Self-Tariffing - essentially having its own intelligence, which allows it to analyse the dialled number against the weekday, time and a charging table to determine the call cost which is then displayed on the LCD.

     (5) Pre-selected Carrier Barring: the oppressive corporate giant that is Telstra did not allow payphone lines to be pre-selected to any other carrier during the pre-2000 era. In effect, tens of thousands of L6 and C4 operators pay full retail rates for each call. In March 2000 Telstra agreed to create a new line after consultation with the ACCC, it was to be identical to the standard payphone line, minus CLM.

     (6) Payphone Lines vs. Normal Lines: payphones such as the TriTel XP1230 utilise a Telephone-style 12 Core cable; whilst the common line you will come across in your own home is a Normal, Austel Approved, Telephone Cable Flat 4 Core. Depending on the area you are in, the copper wires you require for beige boxing are Red and Green or alternatively, White and Blue.

     II. Accessing the Line

     The vast majority of TriTel XP1230's you will come across are encased in a stand rather than a booth. In many instances the aperture between the stand and the wall it is backed against can vary from a centimeter to an inch. If one is able to locate an easily accessible stand with at least one inch of space, gently pry it slightly wider and take a peek behind the metallic hull. You will notice several chords leading from both the mid-section of the payphone and higher up.

     (a) White: the thickest chord (several millimeters short of a centimeter in diameter) encased in corrugated white plastic, is the power source. Do not cut this line.

     (b) Blue: thickness of a standard pen, this houses the phone line and is known as a Telephone-style cable, 12 Core.

     (c) Green-Yellow (striped): several millimeters in diameter, the thinnest; this is the insulated Earth copper wire.

     (d) Black: some TriTel payphones I have come across have a black telephone cable instead, it is a Flat 6 Core cable and is accessed via a hole directly underneath the phone itself but in the actual stand, roughly 5cm in diameter.

     (e) Grey: this is also an additional line found inconjunction with Black 6 Core cables on some TriTel phones and is accessed via the same hole as mentioned above. It is understood to be the Flat Earth copper wire in some areas.

     If you are able to see the phoneline or ascertain its location, it is possible to create a nice hook out of worked silver solder in order to "fish" the chord out from behind the stand for beige-boxing. (See Appendix 5 - Metalwork, Heat Treatment, Tempering to create your own "gaff").

     WARNING. Please make sure you are very certain the line you are about to strip is definitely the telephone line. Colours vary in different areas as I have illustrated above (See d. and e. for some examples of alternatives). A simple, yet effective, method of getting to the copper wires underneath the insulation *instead* of stripping the line or slicing them length-wise with a knife, is to burn off the plastic with a lighter. I *will not* take responsibility for anything you attempt to do based on what you have read - you do so at your own risk.

     III. Pricing

     As mentioned earlier, the corporate behemoth, known as Telstra, charges full retail rates to all payphone operators who are connected to their network. Their payphone division pays an estimated 12 cents per meter pulse, (1 meter pulse = 1 local call). Payphone Operators are thus unable to offer better rates to the End User due to the method by which they are charged.

     TriTel payphones do not need meter pulses to operate (they are Self-Tariffing) and are thus able to pre-select to other carriers, theoretically able to offer better rates.

     Due to Telstra's control of the Phonecard market (for alternative phonecards see Appendix 1 - PayTel Australia) and their barring of TriTel from allowing the XP1230 to read Telstra SmartCards, TriTel has come out with their own brand of Phonecards which are available at various Newsagents in certain regions of the country, at this writing they are still hard to come by.

     Appendix 1 - PayTel Australia
     Almost half a year ago, whilst researching various exotic payphones available around Australia, I came across the PayTel S400 Satellite Payphone. Although I have never seen one let alone operated one before, I can provide you with quite a detailed amount of information on it (all of which I obtained from their website and am essentially presenting here as a means of preservation and future reference). If any of you Melbournites ever come across any of these, or anyone across Australia for that matter, have a good look at them, try various things and email me with some constructive information (Do they ring? Do tonediallers work on them? Is the handset muted for incoming calls? Are there any barred services and so on).

     PayTel payphones are generally found in a variety of locations and are designed for providing remote locations with telephone communication. They utilise wireless technology (Analogue / Digital; Cellular Radio, and/or Satellite) to provide these services in "mobile environments" or where wire connections are not available. They can operate on both credit and phonecards - PayTel is the holder of ISO financial card IIN [I]ssuer [I]dentification [N]umber 836 600. The phonecards use Magnetic Stripe technology encoded with a proprietary data system unique to PayTel. Charges for calls Australia-wide and each of 4 ISD call zones are uploaded into each S400 by data signalling from the PayTel office (think, Telstra MTMS updates). 

     Locations where PayTel S400 Satellite Payphones can be found and are applied include: Military; Coaches; Outback Tours; Oil Rigs; Trains; Freighters; Mining Camps; Roadside Assistance; Isolated Communication; Liners; Remote Events and Emergency Locations.

     PayTel is an entirely Australian owned company and claims to be the only group providing payphones actually designed and manufactured here.

     V. Elasa (Telstra X1/X2)

     Manufactured in Spain, the Elasa model was originally designed for indoor use only but Telstra has utilised it as both an outdoor and indoor semi-supervised location Payphone. MTMS updates are constantly barring certain numbers that phreakers find and exploit excessively (publicly announcing "sensitive" numbers on places such as a BBS is highly frowned upon - this was how the iPrimus DCX and FAST were barred). There are numerous Workarounds publicised by Zaleth in his article and the Method for Un-muting an X2 Smartphone Handset are also included in numerous articles and is the reason for why it is not included here.

     This particular subtitle was included to merely record various other information about the Elasa payphone as well as a list of currently known facts about X2's. The Smartphones are constantly being updated, some are of course not and so the differences vary according to location and other factors.


     (a) The Ringtone: Yes, it is true that *some* X2 payphones have an initial two-tone chime to indicate that there is an incoming call. The vast majority *do not* have any sort of ringtone.

     (b) The Un-Mute: Yes, it is possible to un-mute the handset (refer to numerous other articles detailing this method).

     (c) Calling other X2's: It is possible to call other X2 payphones from an X2 and un-mute the handset for two-way communication. Of course there may also exist some X2's that have this capability barred.

     (d) Calling TriTel XP1230's: *Some* X2's are barred from calling TriTel payphones.

     (e) Workarounds: Yes, these do work and are necessary if you wish to call FAST or the iPrimus DCX.

     (f) Tonediallers: Some X2's will only accept tonedialler DTMF if at least 1 digit has been pressed on the actual keypad, others do not accept tonediallers at all.

     (g) DTMF Time-delay: Almost all X2 Smartphones have a time-delay between pressing the number on the keypad and hearing the actual DTMF being played down the line (this only occurs after several digits have been pressed). It is possible to find some X2's that are not updated and do not have this annoying feature, they simply play the DTMF the moment you press the keypad for as many numbers as you dial.

     (h) Straw-trick: This is pathetic, old and does not work any longer. The vast majority of payphones will not let you complete the call after $1.50 or so has been used up in credit (the line is disconnected and ERROR appears on the screen). I'm am quite sure that it isn't even possible now to do the straw-trick even for that minimal credit (it's been so long...)

     (i) MTMS: this is dialled up automatically by the phone when an excessive amount of unconnected 1800 numbers have been dialled sequentially.

     VT-200M Additional Information:

     (a) Call cost is generally 50 cents per local call, $1 initial call to mobile phones.

     (b) Buttons: Follow On, ReDial, Loud.

     (c) Payphone line: Standard Flat 4 Core Telephone-style cable, [Austel Approved].

     (c) 50 cents must be inserted in order to place a 1800 call, the vast majority of VTC phones I have come across will actually charge you for placing that call - a few simply return the money.

     (d) When attempting to dial a 1800 number without money the first digit registers and the DTMF for 1 is played down the line. However, the following 7 numbers (ie. 800-xxx-x) will not register, after which the phone resets and asks again for 50 cents. A mobile phone used as a tone dialler will not work, even after one button is pressed on the keypad. The "Follow On & ReDial" Workaround pertaining to X2's will not work either since the VTC will only register the initial DTMF tone if no money is placed in.

     (e) VTC payphones can be rung and the line is connected as soon as the receiving party lifts the handset. The ring-tone is similar to that of the L6 Bluephone only slightly higher-pitched and louder in some cases.

     Appendix 5 - Metalwork, Heat Treatment, Tempering
     I. Silver Solder Gaff

     You can purchase pieces of Silver Solder from Hardware supply stores, particularly the larger ones as many of the regular BBC stores in your local area may not actually stock any of it (you'd be surprised). Silver solder is quite literally, solder containing silver - and is a long piece of solder about 3 millimeters in diameter and usually found about a metre long. It is easily recognisable in a brown or shiny grey-brown colour and much more stiffer than flimsy wire coat-hangers or other similar pieces.

     A gaff, by definition, is a device for hooking fish; but in the phreaking sense I apply my miniaturised-gaff device to "fishing" phonelines out from the back of payphones, particularly the TriTel XP1230's as they are accessible this way (the stands are sometimes an inch off the wall). Since pieces of silver solder can be quite long it is effective; an accomplice can stand beside you and hold the gaff in place while you have access to the line and do what you will.

   · Using a strong and larger pair of pincers bend the silver solder at a point no more than a few inches from one side (as you do not want to lose too much of its overall length). It may take some effort in straightening and bending (sometimes a hammer can assist in getting it to the right angle) so that two halves are parallel with one another and there is roughly 1 cm of gap between them (this provides the perfect hook shape at the bend).
   · With the same pair of pincers clip off the shorter half right at the point where the bending stops. Make sure that any sharp edges are smoothed. Keep the long section as straight as possible since it can be quite frustrating attempting to fish for phonelines with a crooked gaff.
   · A pathetic ASCII drawing is provided here for my amusement and also your own. Enjoy. NB. this picture is *greatly* reduced in size.

     II. Lock Picks

     While this topic is not entirely related to anything else in the article, it was put in firstly as a prelude to a future article covering this area; and secondly since the methods for tempering and manipulating metals applies to both the construction of gaffs and picks. I will attempt to apply the metal treatments for lockpicks to making a perfect gaff (for the obsessed).

     Constructing a strong torque wrench is done by choosing a nail that suits the various locks you have been studying. Nails which are roughly .25 cm in diameter, once turned into a torque wrench, suit a majority of locks you may come across. Please note that some Lock Picking articles online refer to the "torque" wrench as a tension wrench. Utilising a propane torch to heat up the nail is ideal, once it glows red gradually remove it from the flame and allow the air to cool it down - this basically softens the metal. You can apply this to the silver solder for making your gaff.

   · At the point at which you intend on bending the silver solder for producing the "hook" tip apply a propane torch flame (or gas stove flame if possible) to the area until it turns red as one does when preparing the torque wrench. Once the silver solder has cooled in the air it is soft and easily manipulable.
   · Bend the silver solder at the softened point so that two halves are parallel with one another and there is roughly 1 cm of gap between them (exactly as you would in the I. Silver Solder Gaff description).
   · With a strong pair of pincers cut off the shorter half right at the point where the bending stops (exactly as you would using the more crude method of gaff construction detailed in I. Silver Solder Gaff above).
   · To harden the hook, now that it has been neatly bent and excess silver solder cut off, you will have to temper it by heating the hook end with the propane torch or gas stove flame till it is bright orange. Once it has reached this state immerse the heated portion in a bucket of ice water. You will end up with one of the strongest and finest constructed Silver Solder Gaffs around.
   · NB. Make sure that the hook-tip is not too sharp, grind it smooth or flatten it and file down the edges manually (you dont want to be "fishing" a line to see if it is the power source or phone cable and end up peircing the insulation!).

     Perhaps this will serve to show neophytes entering the scene and wondering how they can start learning more, that the value of research is immeasurable. It may take hours, even days before you find what you are looking for, but the rewards far exceed the cost. The most useful search engine of them all in my own opinion is the wondrous
