Raise your hand if you thought a song called #dtmf had to do with #phone numbers

๐ŸŽถ๐Ÿ“ฑ Behold, a French dev-student-DJ-game-master has cracked the code to send #DTMF #tones on #Android without monopolizing your calls. Apparently, all it took was a sprinkle of #EDM magic and the dreams of every Android user who just can't resist the sweet symphony of touch-tone dialing. Now that's a real hit! ๐Ÿ˜‚๐Ÿ”Š

I recently created my own website! For all of my telephone related ridiculousness. It's a WIP and there will be plenty more to come as I have more time to sit down and add information/customize my webpage!

Supercat Telephone

Rotary phones were in use long after that in Canada, and probably other places, but touch-tone was also available. In the late 80s/early 90s I still had a line that would only do pulse dialing, because touch-tone dialing was an add-on charge with the phone company where I lived.

It was a significant amount; just adding touch-tone support increased the monthly bill by almost 10%. Yes, this was a BS charge, because it was just a flag they set on your account. It didn't cost them anything to provide tone dialing. They still do the same thing with caller-ID, so I don't have it. "We don't care. We're the phone company; we don't have to."

At the time, many (perhaps most) phones you could buy had push-button dialing, but there was a switch on the phone to choose pulse or tone dialing. If you set it to pulse, you'd push the 7 button, and then you'd hear 7 clicks, etc.

So kind of "hybrid dialing".

@mediaarchaeologylab I'd likely modify it into a #touchtone-style analog landline phone since any cheap modern landline phone has the parts for that and the handset would basically be ised for the keyboard matrix and sound.

And that could then be adapted to VoIP (ethernet and/or WiFi) or even GSM/VoLTE with commercial off-the-shelf parts...

So it is possible to turn it into a useable device again - which is desireable if one needs a functioning prop or wants to make people scratch their heads.

anyone know of a good online or command-line #DTMF #TouchTone generator?

[this pony is not doing sick Hacks]

Wiedergefunden und neue Batterien eingesetzt.

Unglaublich, wie hรคufig es noch Hotlines gibt, bei denen man vorab mit #Touchtone auswรคhlen soll und nicht weitergeschaltet wird, wenn man das nicht tut.

DECT-Headset an der Telefonanlage. Mal schauen, ob der Touchtone Generator bei dem Problem hilft.
