...and I hope you've learned to sanitize your DTMF inputs
I always sanitized my DTF inputs, as my last tests failed.

Re: I broke IKEA (2023)
#22Long 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 m…
Back when international phone calls were a real thing, messing with answering machines that had default settings was a typical fraud vector. People would change the message to say 'I accept' a couple dozen times. Then, they'd lace a collect call with a third party payer, pointed at said answering machine... which accepted the charges. Just not best done from one's home phone, as sufficient charges pointing to the same number would risk attention.

#23Website doesn't like it if you block third-party content (using uMatrix). It loads and then disappears a few seconds later.
Works fine here.

#25That Windows alert sound in between the glitching binary-dump-as-audio sounds was just too funny.

#26As 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…
There may be secrets in that audio - actual passwords and whatnot.

Works for me. I enabled the 1st party and cohost.org rows plus the css and images columns. Maybe it's because of another addon?

I was thinking the same thing! I don't get spam calls often but when I do I really want to punish them for wasting my time.
Jolly Rodger Telephone service has worked wonderfully for me.
I'm on the floor just listening to the sample calls.

Might be a fun follow-up to try and decode whatever's in there.

You can hear the windows XP message box sound right before that. Which surprises in two ways: a) they're still using windows XP (ok well we still do too at work for some appliance from the power company). b) it seems you're not hooked into the machine via some modem or virtual-something over lan, but something that connects to the sound card, otherwise I've no idea how system sounds that always play on the default card would end up in the phone call. That means there's one machine handling one call at a time.
