Recording the sounds that were emitted by a payphone when inserting coins and then playing them back into a payphone handset to get free calls ("red boxing") was a thing that def--err, maybe worked hypothetically I do not know and definitely never tried this absolutely not no way...
- EvanAnderson 6y agoUnderstanding the difference between in-band and out-of-band signaling is valuable. Pay phones and how a red box exploits in-band signaling has been an example I've used in teaching. I find it less difficult to relate than the MF signaling that blue boxes exploited.
- Scoundreller 6y agoYeah, last I remember it was UPS that they transferred my call and then I heard a couple tones and thought “ohhh, in-band signaling”.
