When a coin is inserted into a payphone, the payphone emits a set of tones to ACTS (Automated Coin Toll System). Red boxes work by fooling ACTS into believing you have actually put money into the phone. The red box simply plays the ACTS tones into the telephone microphone. ACTS hears those tones, and allows you to place your call. The actual tones are:
Nickel Signal 1700+2200 0.060s on Dime Signal 1700+2200 0.060s on, 0.060s off, twice repeating Quarter Signal 1700+2200 33ms on, 33ms off, 5 times repeating
Canada uses a variant of ACTSD called N-ACTS. N-ACTS uses different tones than ACTS. In Canada, the tones to use are:
Nickel Signal 2200hz 0.060s on Dime Signal 2200hz 0.060s on, 0.060s off, twice repeating Quarter Signal 2200hz 33ms on, 33ms off, 5 times repeating
Red boxes are commonly manufactured from modified Radio Shack tone dialers, Hallmark greeting cards, or made from scratch from readily available electronic components.
To make a Red Box from a Radio Shack 43-141 or 43-146 tone dialer, open the dialer and replace the crystal with a new one. The purpose of the new crystal is to cause the * button on your tone dialer to create a 1700Mhz and 2200Mhz tone instead of the original 941Mhz and 1209Mhz tones. The exact value of the replacement crystal should be 6.466806 to create a perfect 1700Mhz tone and 6.513698 to create a perfect 2200mhz tone. A crystal close to those values will create a tone that easily falls within the loose tolerances of ACTS. The most popular choice is the 6.5536Mhz crystal, because it is the easiest to procure. The old crystal is the large shiny metal component labeled "3.579545Mhz." When you are finished replacing the crystal, program the P1 button with five *'s. That will simulate a quarter tone each time you press P1.
3. Where can I get a 6.5536Mhz crystal?
Your best bet is a local electronics store. Radio Shack sells them, but they are overpriced and the store must order them in. This takes approximately two weeks. In addition, many Radio Shack employees do not know that this can be done.
Or, you could order the crystal mail order. This introduces Shipping and Handling charges, which are usually much greater than the price of the crystal. It's best to get several people together to share the S&H cost. Or, buy five or six yourself and sell them later. Some of the places you can order crystals are:

4. Which payphones will a Red Box work on?
Red Boxes will work on telco owned payphones, but not on COCOT's (Customer Owned Coin Operated Telephones).
Red boxes work by fooling ACTS (Automated Coin Toll System) into believing you have put money into the pay phone. ACTS is the telephone company software responsible for saying "Please deposit XX cents" and listening for the coins being deposited.
COCOT's do not use ACTS. On a COCOT, the pay phone itself is responsible for determining what coins have been inserted.
5. How do I make local calls with a Red Box?
Payphones do not use ACTS for local calls. To use your red box for local calls, you have to fool ACTS into getting involved in the call.
One way to do this, in some areas, is by dialing 10288-xxx-xxxx. This makes your call a long distance call, and brings ACTS into the picture.
In other areas, you can call Directory Assistance and ask for the number of the person you are trying to reach. The operator will give you the number and then you will hear a message similar to "Your call can be completed automatically for an additional 35 cents." When this happens, you can then use ACTS tones.
Blue boxes use a 2600hz tone to size control of telephone switches that use in-band signalling. The caller may then access special switch functions, with the usual purpose of making free long distance phone calls, using the tones provided by the Blue Box.
This FAQ answer is excerpted from a message posted to Usenet by Marauder of the Legion of Doom.
Somewhere along the line I have seen reference to something similar to "Because of ESS Blue boxing is impossible". This is incorrect. When I lived in Connecticut I was able to blue box under Step by Step, #1AESS, and DMS-100. The reason is simple, even though I was initiating my call to an 800 number from a different exchange (Class 5 office, aka Central Office) in each case, when the 800 call was routed to the toll network it would route through the New Haven #5 Crossbar toll Tandem office. It just so happens that the trunks between the class 5 (CO's) and the class 4 (toll office, in this case New Haven #5 Xbar), utilized in-band (MF) signalling, so regardless of what I dialed, as long as it was an Inter-Lata call, my call would route through this particular set of trunks, and I could Blue box until I was blue in the face. The originating Central Offices switch (SXS/ESS/Etc..) had little effect on my ability to box at all. While the advent of ESS (and other electronic switches) has made the blue boxers task a bit more difficult, ESS is not the reason most of you are unable to blue box. The main culprit is the "forward audio mute" feature of CCIS (out of band signalling). Unfortunately for the boxer 99% of the Toll Completion centers communicate using CCIS links, This spells disaster for the blue boxer since most of you must dial out of your local area to find trunks that utilize MF signalling, you inevitably cross a portion of the network that is CCIS equipped, you find an exchange that you blow 2600hz at, you are rewarded with a nice "winkstart", and no matter what MF tones you send at it, you meet with a re-order. This is because as soon as you seized the trunk (your application of 2600hz), your Originating Toll Office sees this as a loss of supervision at the destination, and Mutes any further audio from being passed to the destination (ie: your waiting trunk!). You meet with a reorder because the waiting trunk never "hears" any of the MF tones you are sending, and it times out. So for the clever amongst you, you must somehow get yourself to the 1000's of trunks out there that still utilize MF signalling but bypass/disable the CCIS audio mute problem. (Hint: Take a close look at WATS extenders).
A Black Box is a resistor (and often capacitor in parallel) placed in series across your phone line to cause the phone company equipment to be unable to detect that you have answered your telephone. People who call you will then not be billed for the telephone call. Black boxes do not work under ESS.

An ANAC (Automatic Number Announcement Circuit) number is a telephone number that plays back the number of the telephone that called it. ANAC numbers are convenient if you want to know the telephone number of a pair of wires.
11. What is the ANAC number for my area?
How to find your ANAC number:
Look up your NPA (Area Code) and try the number listed for it. If that fails, try 1 plus the number listed for it. If that fails, try the common numbers like 311, 958 and 200-222-2222. If you find the ANAC number for your area, please let us know.
Note that many times the ANAC number will vary for different switches in the same city. The geographic naming on the list is not intended to be an accurate reference for coverage patterns, it is for convenience only.
Many companies operate 800 number services which will read back to you the number from which you are calling. Many of these require navigating a series of menus to get the phone number you are looking for. Please use local ANAC numbers if you can, as overuse or abuse can kill 800 ANAC numbers.

An non-800 ANAC that works nationwide is 404-988-9664. The one catch with this number is that it must be dialed with the AT&T Carrier Access Code 10732. Use of this number does not appear to be billed.
Note: These geographic areas are for reference purposes only. ANAC numbers may vary from switch to switch within the same city.

12. What is a ringback number?
A ringback number is a number that you call that will immediately ring the telephone from which it was called.
In most instances you must call the ringback number, quickly hang up the phone for just a short moment and then let up on the switch, you will then go back off hook and hear a different tone. You may then hang up. You will be called back seconds later.
13. What is the ringback number for my area?
An 'x' means insert those numbers from the phone number from which you are calling. A '?' means that the number varies from switch to switch in the area, or changes from time to time. Try all possible combinations.
If the ringback for your NPA is not listed, try common ones such as 951-xxx-xxxx, 954, 957 and 958. Also, try using the numbers listed for other NPA's served by your telephone company.
Note: These geographic areas are for reference purposes only. Ringback numbers may vary from switch to switch within the same city.

This FAQ answer is excerpted from ToneLoc v0.99 User Manual by Minor Threat & Mucho Maas.
Loops are a pair of phone numbers, usually consecutive, like 836-9998 and 836-9999. They are used by the phone company for testing. What good do loops do us? Well, they are cool in a few ways. Here is a simple use of loops. Each loop has two ends, a 'high' end, and a 'low' end. One end gives a (usually) constant, loud tone when it is called. The other end is silent. Loops don't usually ring either. When BOTH ends are called, the people that called each end can talk through the loop. Some loops are voice filtered and won't pass anything but a constant tone; these aren't much use to you. Here's what you can use working loops for: billing phone calls! First, call the end that gives the loud tone. Then if the operator or someone calls the other end, the tone will go quiet. Act like the phone just rang and you answered it ... say "Hello", "Allo", "Chow", "Yo", or what the fuck ever. The operator thinks that she just called you, and that's it! Now the phone bill will go to the loop, and your local RBOC will get the bill! Use this technique in moderation, or the loop may go down. Loops are probably most useful when you want to talk to someone to whom you don't want to give your phone number.
15. What is a loop in my area?
Many of these loops are no longer functional. If you are local to any of these loops, please try them out an e-mail me the results of your research.

CNA stands for Customer Name and Address. The CNA number is a phone number for telephone company personnel to call and get the name and address for a phone number. If a telephone lineman finds a phone line he does not recognize, he can use the ANI number to find it's phone number and then call the CNA operator to see who owns it and where they live.
Normal CNA numbers are available only to telephone company personnel. Private citizens may now legally get CNA information from private companies. Two such companies are:
Unidirectory (900)933-3330 Telename (900)884-1212
Note that these are 900 numbers, and will cost you approximately one dollar per minute.
If you are in 312 or 708, AmeriTech has a pay-for-play CNA service available to the general public. The number is 796-9600. The cost is $.35/call and can look up two numbers per call.
If you are in 415, Pacific Bell offers a public access CNA service at (415)705-9299.
If you are in Bell Atlantic territory you can call (201)555-5454 or (908)555-5454 for automated CNA information. The cost is $.50/call.

Scanning is dialing a large number of telephone numbers in the hope of finding interesting carriers (computers) or tones.
Scanning can be done by hand, although dialing several thousand telephone numbers by hand is extremely boring and takes a long time.
Much better is to use a scanning program, sometimes called a war dialer or a demon dialer. Currently, the best war dialer available to PC-DOS users is ToneLoc from Minor Threat and Mucho Maas. ToneLoc can be FTPed from ftp.paranoia.com.
A war dialer will dial a range of numbers and log what it finds at each number. You can then only dial up the numbers that the war dialer marked as carriers or tones.
This FAQ answer is excerpted from 2600, Spring 1990, Page 27.
In some places, scanning has been made illegal. It would be hard, though, for someone to file a complaint against you for scanning since the whole purpose is to call every number once and only once. It's not likely to be thought of as harassment by anyone who gets a single phone call from a scanning computer. Some central offices have been known to react strangely when people start scanning. Sometimes you're unable to get a dialtone for hours after you start scanning. But there is no uniform policy. The best thing to do is to first find out if you've got some crazy law saying you can't do it. If, as is likely, there is no such law, the only way to find out what happens is to give it a try.

Notes:
[C1] - Means code used for Cellular One service
[1] - for cellular in Pittsburgh, PA A/C 412 in some areas
[2] - indicates that you are not local and maybe how to reach you
[3] - found in Pac Bell territory; Intercom ring causes a distinctive
ring to be generated on the current line; Hold keeps a call
connected until another extension is picked up
[4] - applied once before each call
[5] - A.C.R. blocks calls from those who blocked Caller ID
(used in C&P territory, for instance)
[6] - cancels further return attempts
[7] - *82 (1182) has been mandated to be the nationwide code for
"Send CLID info regardless of the default setting on this
phone line."
[M: *xx] - alternate code used for MLVP (multi-line variety package)
by Bellcore. It goes by different names in different RBOCs.
In Bellsouth it is called Prestige. It is an arrangement of
ESSEX like features for single or small multiple line groups.
The reason for different codes for some features in MLVP is that
call-pickup is *8 in MLVP so all *8x codes are reassigned *5x

Always test as much as possible before relying on any method of blocking Caller-ID. Some of these methods work in some areas, but not in others.
Dial *67 before you dial the number. (141 in the United Kingdom)
Dial your local TelCo and have them add Caller-ID block to your line.
Dial the 0 Operator and have him or her place the call for you.
Dial the call using a pre-paid phone card.
Dial through Security Consultants at (900)PREVENT for U.S. calls
($1.99/minute) or (900)STONEWALL for international calls ($3.99/minute).
Dial from a pay phone. :-)
A PBX is a Private Branch Exchange. A PBX is a small telephone switch owned by a company or organization. Let's say your company has a thousand employees. Without a PBX, you would need a thousand phone lines. However, only 10% of your employees are talking on the phone at one time. What if you had a computer that automatically found an outside line every time one of your employees picked up the telephone. With this type of system, you could get by with only paying for one hundred phone lines. This is a PBX.
A VMB is a Voice Mail Box. A VMB is a computer that acts as an answering machine for hundreds or thousands of users. Each user will have their own Voice Mail Box on the system. Each mail box will have a box number and a pass code.
Without a passcode, you will usually be able to leave messages to users on the VMB system. With a passcode, you can read messages and administer a mailbox. Often, mailboxes will exist that were created by default or are no longer used. These mailboxes may be taken over by guessing their passcode. Often the passcode will be the mailbox number or a common number such as 1234.
33. What are the ABCD tones for?
The ABCD tones are simply additional DTFM tones that may be used in any way the standard (0-9) tones are used. The ABCD tones are used in the U.S. military telephone network (AutoVon), in some Automatic Call Distributor (ACD) systems, for control messages in some PBX systems, and in some amateur radio auto-patches.
In the AutoVon network, special telephones are equipped with ABCD keys. The ABCD keys are defined as such:
A - Flash B - Flash override priority C - Priority communication D - Priority override
Using a built-in maintenance mode of the Automatic Call Distributor (ACD) systems once used by Directory Assistance operators, you could connect two callers together.
The purpose of the Silver Box is to create the ABCD tones.

34. What are the International Direct Numbers?
The numbers are used so that you may connect to an operator from a foreign telephone network, without incurring long distance charges. These numbers may be useful in blue boxing, as many countries still have older switching equipment in use.
