Check out this robocall blocker project from Alex Ruiz, shared by FreeIO.org:
I recently submitted a solution for a government initiative here in the USA to stop those pesky automated telemarketing phone calls. You can see the details here:
My solution was prototyped using a RPi and an off-the-shelf Analogue Telephone Adapter and it works great. Being an independent coder, the advantages the RPi presented as a development platform both in cost and flexibility made it an obvious choice for writing experimental phone software. Because of the low cost, I was able to successfully fund the development and beta distribution of units on my own. This helps enormously, as I can now claim that my solution is not theoretical and is working in a real business environment.
I was able to fully meet the criteria of the FTC’s challenge entirely.
And all of this was only possible with the RPi.
Again, I cant thank you guys enough for this wonderful piece of hardware and the personal attachment I’ve grown for it. This device showed me my own potential as a developer and for that, I am very grateful.
