A DATU. After the tone, we played the access code (we'll leave it to you to decode the digits, but it's not exactly a tough one) followed by a single 1. Then we were prompted with "Dial 7 Digit Subscriber Line Number". We don't know any valid numbers in 732 so we guessed at one, and typed 958-6111. Apparently this is not even a valid prefix.

While recording 89996563.MP3, we observed a little glitch just before the recording. We wondered if what we were hearing was simply line noise, so we amplified it and slowed it to one quarter speed. Could this be digital crosstalk? Leakage? The remnants of an incompletely filtered out-of-band signal? Have a look and see if you can identify this! Recorded 2003/10/07 from 250

Synthesized Voice: "This is LBB 131.70" followed by some DTMF *'s. Hitting 3* produced a "Testing, Track 3" message.
Recorded 2003/10/05 from 250.
Update 2004/03: Extensive googling has turned up some interesting facts about this "mystery number". For starters, the 806 area code includes Lubbock, Texas. This is relevant because LBB happens to be the FAA airport code for Lubbock. 131.70 is the frequency used by Southwest Airlines for ground operations and dispatch at many airports, including KLBB. So, this line is likely a maintenance dialup for a VHF repeater owned by Southwest at Lubbock International Airport. Some of the astute among you may point out that L B B is pronounced in English rather than in phonetics (Lima Bravo Bravo) as would be used by both aviators and radiomen, but remember that this is a dialup and this message is almost certainly only heard on the line. The actual number of this line is no longer being listed here due to the possibility that messing with it could cause possible safety problems.

Millennium Payphone Rings!

This is the sound of a Nortel Millennium M1231 Payphone ringing!

There has been some heated discussion in alt.phreaking in recent months as to whether a Nortel Millennium payphone is capable of ringing. The answer, of course, is yes, and this file is the sound the phone makes. We at Whirlwind believe that there is a progressive campaign going on in many areas to make all payphones outgoing-only, which means that they are connected to phone lines that cannot accept incoming calls (callers get a recording). This of course is a line setting and not a property of the Millennium (or any other) phone, and while the phone companies have made *most* Nortel Millenniums undialable, there are a few which they "forgot". This one is at 250-389-9075. Added June 10, 2000

REAL Red Box tones!

This is as real as it gets, boys and girls - these are the tones from an actual GTE/Automatic Electric ACTS Payphone. Note the poor quality of the speech compared with the excellent quality of the tones - there is a distortion device on the handset mic! That is how they prevent red boxers in 604/250! Note also that these are the standard 1700/2200 tones, not plain 2200 as some in alt.2600 say Canadian phones are supposed to use. By the way, the phone kept my coins. This file cost me 65 cents to make! To paraphrase TAP, "BC Tel is a cheap mother!"
