Tricks and Treats of the AUTOVON by N-Tolerant The AUTOVON (Automatic Voice Network) is the military's worldwide switch system used to link all DOD installations together on one telephone network. It is not a secure communications system. Classified information is discussed over the AUTOVON only when a secure telephone such as a STU-3 or a STU-5 is used. Otherwise, it works much like the normal telephone systems you use every day. The functional switching technology, however, is very similar to that of the outdated telephone networks of years long past. I recommend that you read ShAdOOwRuNnErs "Intro to Automatic Voice Network Commonly known as AUTOVON" parts one thru three for more information, including an introduction, how to get into AUTOVON using a silver box, and a few tricks to do once you're inside. That article can be found at: ftp://ftp.fc.net/pub/phrack/underground/misc In this article I will cover the following: 1. Common Features 2. "Area Codes" 3. Installation Prefixes 4. Other Phunee Stuff 1. Common Features of AUTOVON Systems Once you are connected to the AUTOVON system, there are certain procedures that you can perform from your phone which activate and cancel functional features of the system. Some are trivial, but others can be fun if the user is creative enough. These are performed using a standard Touch-Tone phone. Some commands vary from installation to installation, but most are universal. Automatic Call Back If the number you are trying to call is busy, this will cause the other party's phone to ring once they hang up. Yours will also ring, and once both ends are off-hook, the two phones will be connected. Active: 1. Lift receiver. 2. Dial number. 3. When busy signal is received, press and release the switchhook. 4. When dialtone is received, dial "161". 5. Listen for positive acknowledgment tone (wavering continuous tone). 6. Replace receiver. 7. Cancel: 1. Lift receiver. 2. Listen for dialtone. 3. Dial "162". 4. Listen for positive acknowledgment tone. 5. Replace receiver. Call Transfer To patch someone who calls you to another number. 1. Press switchhook to put incoming call on hold. 2. Listen for continuous dialtone. 3. Dial desired number. (At this point, you can, but don't have to, wait for the third-party to answer and announce the caller before you hang up.) 4. Replace receiver. Note: When you have a third-party on line and the original caller on hold, you can press and release the switchhook for a three-party conference call. Malicious Call Identification Self-explanatory. Most of us were busted with something like this in our younger years, before we got smart. With caller still on the line: 1. Depress switchhook 2. Listen for continuous tone. 3. Dial "12". 4. Continue talking. 5. When conversation ends, dial "114". Caller hangs up. 6. Lift receiver. 7. Listen for busy tone. 8. Within 3 seconds, depress switchhook. 9. Listen for continuous dialtone. 10. Dial "12". 11. Replace receiver - Lift receiver. 12. Dial "114". Call Forwarding Forward incoming calls to another number. Activate: 1. Lift receiver. 2. Listen for continuous dialtone. 3. Dial "131" and second-part number. 4. Listen for wavering continuous tone (positive acknowledgment). 5. Replace receiver. Cancel: 1. Lift receiver. 2. Listen for intermittent tone. 3. Dial "132". 4. Listen for wavering continuous tone. 5. Replace receiver. Deactivate (Lock) Phone No incoming or outgoing calls. 1. Lift receiver. 2. Listen for dialtone. 3. Dial "143". 4. Replace receiver. Activate (Unlock) Phone 1. Lift receiver. 2. Listen for intermittent tone. 3. Dial "142". 4. Replace receiver. 2. "Area Codes" An AUTOVON telephone number is in the same format as a regular U.S. number [(NPA) NXX-XXX]. The first part, which is the area code in normal numbers, identifies the theater to which you are calling. The AUTOVON codes are as follows: CONUS (Continental U.S.) - 312 Canada - 312 Europe - 314 Asia/Pacific - 315 Alaska - 317 Caribbean - 313 Persian Gulf - 316, 318 3. Installation Prefixes Each DOD installation has its own three-digit prefix (like cities on civilian systems). Some larger military bases or installations may have more than one prefix. It would take way too much space to list all of them, but here's an abbreviated list: CONUS (312) Ft. McClellan, AL - 865 Yuma Proving Ground, AZ - 879 Ft. Irwin, CA - 470 Ft. Carson, CO - 691 Ft. McNair, DC - 227 Ft. Leavenworth, KS - 552 Ft. Meade, MD - 923 U.S. Military Academy, NY - 688 Ft. Sam Houston, TX - 471 Port Hueneme Naval Construction Battalion Ctr, CA - 551 Naval Security Station, DC - 288 Key West Naval Air Station, FL - 483 Great Lakes Naval Training Center, IL - 792 U.S. Naval Academy, MD - 281 McClellan AFB, CA - 633 Los Angeles AFB, CA - 833 U.S. Air Force Academy, CO - 333 Mountain Home AFB, ID - 728 Andrews AFB, MD - 858 Hanscom AFB, MA - 478 Nellis AFB, NV - 682 Tinker AFB, OK - 884 Lackland AFB, TX - 473 McChord AFB, WA - 984 Hill AFB, UT - 777 The Pentagon, DC - 227 Canada (312) Air Command Winnipeg - 826 Air Defense Headquarters, Ontario - 628 Calgary CFB - 620 Military Area Pacific Headquarters, Vancouver - 252 Europe (314) Stuttgart, Germany - 420 Mannheim, Germany - 380 Vicenza, Italy - 634 Naples, Italy - 625 Rota, Spain - 727 Moron, Spain - 722 Ramstein, Germany - 480 Mildenhall, UK - 238 Aviano, Italy - 632 Incirlik, Turkey - 676 Asia/Pacific (315) Camp Red Cloud, Korea - 732 Camp Humphreys, Korea - 753 Yokota AB, Japan - 225 Misawa AB, Japan - 226 Kadena AB, Japan - 630 Kunsan AB, Korea - 782 Anderson AFB, Guam - 366 Pearl Harbor Naval Complex, HI - 471 Hickam AFB, HI - 471 Alaska (317) Ft. Richardson - 384 Adak Naval Air Facility - 692 Caribbean (313) Howard AFB, Panama - 284 Ft. Buchanan, Puerto Rico - 740 Air National Guard, San Juan, Puerto Rico - 740 Persian Gulf Dharan (318) - 828 Riyadh (316) - 435 4. Other Phunee Stuff If you are going to explore the world of the AUTOVON, there are some bits of knowledge that might make your journey more interesting, useful, and phun. Here are a few of those bits: The AUTOVON prefix for an installation is not the same as the civilian prefix. The last part of the number is the same for wherever you are calling, but the prefix will rarely, if ever, be the same. Not all phone lines on the AUTOVON have worldwide capability. Some only have theater capability. For instance, most phones in the European theater (Great Britain, Germany, Italy, etc.) can call AUTOVON phones within Europe, but no beyond. Common worldwide-capable lines are installation operator, installation commander, other high-ranking officials/officers, and technical control facility lines. Worldwide lines are much more common at stateside installations. Note: All AUTOVON phones can receive worldwide calls. The common number for the installation operator is "XXX-1110" ("XXX being the prefix for that installation). The operator can do just about anything, such as transfer your call to a local number or patch you through to another installation. It sometimes takes social engineering to get a favor from a switch operator. It also depends on the installation policy on such matters. I recommend operators at Air Force bases. They seem more willing that others such as Army or Navy. Some places have automated switches that will allow you to dial out to a local number (or toll-free number). One such place is Fort Bragg, NC. You dial (312) 236-0001 and a recording will give you some options. Sometimes AUTOVON calls are cut-off. This could be because of a time limit. Sometimes calls are preempted, though. This means that the trunk you were using was seized by another phone by way of priority keys.
