Long ago I got a Psion Series 5. One feature was that it could dial a phone number (output the DTMF) for you. Messing around I've day I realized a contact could have a very long phone number. This was also back in the day when answering machines existed and many had a 2 digit code you could punch in to get into the menu from the outside line.
My contact called Answering Machine had a very long phone number that got me into more than one answering machine. Once in, it was fun to change their outgoing message. One friend was convinced that I must have climbed the back of his apartment building to get in the open 3rd story window to change the message. That would have been cool, but a string of DTMF was much easier!

I read the text first, then listened to the audio, and was shocked at how good that transcription is.

As someone who’s had some incidents with DSP code, the end of the recording sounds like it may be playing some part of memory that isn’t an audio buffer. I wonder if there’s actually a “DTMF injection” possibility here…

That Windows alert sound in between the glitching binary-dump-as-audio sounds was just too funny.

I'd love to know how that PBX is set up.

Haha, awesome. Would be good to get the uncompressed audio, I bet you could decode that binary stream into bytes.

That modem comms sound is IKEA's backhacking attempt. Much more advanced than touch tones.
Beware!

I like how they can animate their posts in this cohost social networking site. (See the transcript section)

...and I hope you've learned to sanitize your DTMF inputs

I wonder if those sounds are they sounds of bits/byte data. There’s some regularity to it so it’s likely somewhat structured.

Website doesn't like it if you block third-party content (using uMatrix). It loads and then disappears a few seconds later.

The last 15 seconds sounds like it hit the runout groove on the IKEA phone system vinyl!

I'd love to know what actually happened back there.

Brilliant. Thank you for sharing.

This feels extremely legally risky
EDIT: I'm getting downvoted. I think people have gone to prison for a lot less than this, at least in the US, please be careful and playfulness is not a legal defense
