Got this call not long ago... and Google Voice automatically flagged it as SPAM and send it to hell.. I mean voicemail.

If your TelCo has the Simultaneous Ring feature, ENABLE IT and point it to your Google Voice number. So now, every call to your phone number will also ring your Google Voice number.
- What does this do? It gives you a record of EVERY call to your phone
- What good does THAT do? You can then use Google Voice to block those numbers, so the next time any of the blocked numbers call your phone again, Google Voice will intercept and block it.
- How is this different from using the TelCo to block the numbers? When Google Voice blocks a number it plays the "NOT IN SERVICE" tone and message
- As an added bonus, Google Voice automatically detects known SPAMMERS and sends them to voicemail even if they've never called your phone before - yes, exactly like Gmail but for phones

I don't work for Google, but just thought I'd share because these f-ers are really pissing me off so the more ways we can screw them over the better. If you have a third-party call blocker, that'd work too. Spread the word.
