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:
http://robocall.challenge.gov/
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.
Each Friday is PiDay here at Adafruit, be sure to check out our posts, tutorials and new Raspberry Pi related products. Have you tried the new “Adafruit Raspberry Pi Educational Linux Distro” ? It’s our tweaked distribution for teaching electronics using the Raspberry Pi. But wait, there’s more! Try our new Raspberry Pi WebIDE! The easiest way to learn programming on a Raspberry Pi.
We now have Raspberry Pi Model B with 512MB RAM in stock and shipping now!

The telephone to analog converter plus the router look like this project will cost some money but does this phone only work over the internet (VOIP)? If so, is it impractical for regular phone users?
I do like the project and I will want one but I think I will keep most callers on a permanent list of “Do not call”.
