I created a version of this in 2006 (I think), called Getmooh.com - Get Me Out Of Here. The idea was to get people out of bad dates with an automated call.

I used the Skype API with VB6 and some natural voice libraries from AT&T. We mostly got used for prank calls with pre-recorded messages we had. Worked OK. But cost us money and I got bored once it was built. We got maybe 60,000 sign ups I think.

I'm pretty sure this was a feature of an old dumbphone, you could set it up so that holding down the number 5 (say) on the key pad would trigger a 'call'. Might have been a Samsung?

I hand an old Nokia (That had a sliding keyboard !!) with this feature (press down volume 4 times), it also had a scheduling feature with personalized ring-tone, number and display name!

I have a Samsung GT E1200 and the fake call is triggered after a configurable timeout by pressing the down button four times while the screen is locked.

Guess it could have been. Our system didn't just call though, you could answer and it talked to (well, at) you.

My old Nokia had that. Used it sometimes for sure.
