Help identifying tone

5 posts in this topic

Hi everyone. It's my first time here, so sorry if I do something weird/stupid.

I wanted to know if you guys can identify a phone signal I got:

If you jump to the "TONE STARTING" marker, you'll hear some kind of modem-like sound repeated three times... does anyone know what that sounds means? Is it waiting for some kind of input?

Thank you very much!

Edit:

Ok, I think I should explain better. This wiki explains in details our "operation": http://otp22.referata.com/. Long story short, we found a weird phone number that sounded like a number station and we've been decoding stuff out of that phone number for a while. In the latest "twist", they have been transmitting messages in ITA2, which pointed to the phone number I linked above. The ITA2 message on that phone was decoded as:

DEADMANSWITCHTRIPENTRBELLAGENTCODETOREACTIVATEAGENTSYSTEM

My guess is that I have to enter the agent code after that modem-like sound. And, indeed, when I type something after that, I get some kind of response from the phone system (check the difference in the end):

So, well... I was thinking maybe you guys could help identify all the modem-like sounds? What do they mean? Specially this last one, after I entered the 99286 code (check the notes).

Any help is really appreciated. Thank you!

Ok, I just realized someone named 0004 dumped one of our wiki pages on a post earlier. I don't know who he is, but the page he dumped is this one: http://otp22.referata.com/wiki/Agent_Codes

What is otp for?. Shortwave club for number stations or what?. Strange but interesting page.

I can't say I've heard anything like this before. The people who run phone networks tend to not be very inventive with data, so any modem you find will usually sound something like these two;

712-374-1242 is an example of a higher speed modem - anything from about 9600 baud to 56k, while 360-676-0015 is a handshake from a lower speed modem, usually anything from 300 to maybe 4800 baud, I believe 4800 might use the more modern handshake.

Anything proprietary tends to sound more or less the same, but has some slight difference to stop an off the shelf modem from connecting.

I wish I could help more, but what's interesting about your recording is the tone at the distant end isn't waiting for a handshake or anything, as if it was designed for one-way transmission. In phone situations, that's almost never the case. Someone is probably generating this with the intent of transmitting it over any sound-based medium.

By the way, is your phone okay? It sounds like some kind of VoIP phone with a stomach virus.

712-374-1242 - Answers at 9600 baud. It says "ENTER PASSWORD" when it answers. I tried a couple of things, then it said ACCESS DENIED and dropped carrier.

360-676-0015 - Answers at a whopping 1200 baud. All it does is send a question mark "?" followed by a carriage return/line feed. No matter what I typed it I couldn't get it to do anything else.

I looked through the page and seems a type of arg game. For asecond i thought there were actually real numbers. Is a fictional set-up or is anything real in the otp22 page?.
