This may not be the place for this post, and if that is the case please advise where to ask this question.

I am trying to make my home phone number require that ANYONE who calls it must enter a numeric code, defined by me, before their call will be connected and cause my phone to ring. This is because no matter how many times I switch my phone number, someone has always had it previously, and I get their collections/etc calls.

I have seen this... https://murphy101blog.wordpress.com/2013/11/03/raspberry-pi-telephone-number-blocker/ using a Raspberry Pi, but I do not want to block based on a blacklist, I want to block ALL and require they enter a numeric code before they get through.

Does anyone have any suggestions as to how I can go about this? From all the searching I've done I can only seem to find devices that block based on a blacklist, devices that prompt the caller to speak their name, etc before the call is connected.

Any suggestions on what I can use or if there are any devices in existence already, what they are called?

thank you!

UPDATE

After searching some more, I've found that the open-source software framework Asterisk is now available for Raspberry Pi http://www.raspberry-asterisk.org/. I'm wondering, could this be the answer to this question?

I also found this script which SEEMS to do what I want. https://www.voip-info.org/wiki/view/Authenticate+Users+by+Caller+ID+or+PIN+-+password

  • Modems generally respond to Hayes commands, I'd presume those include a way to deal with number-tones but I can't say for sure. Probably the best place to ask is S.O.; they have a tag for this. – goldilocks May 11 '17 at 16:04
  • @goldilocks - lol I did ask on S.O. and they referred me here. – Phil May 11 '17 at 16:05
  • As in, you already asked a specific question about AT commands? I'm not seeing that but perhaps you deleted the question. I'm fine with leaving this open here, but if you want to move forward, read up on the Hayes stuff and/or come up with an appropriate question for S.O. ;) – goldilocks May 11 '17 at 16:08
