For the record, Google Voice is actually pretty anonymous. If you attach your real phone number to it, any calls to the Voice number would redirect to your real one *unless* you are logged on. Meaning, if you are
currently logged in to your Google Voice account via PC, then calls at the time or during your time logged in will ring on screen, assuming your browser is working fine, and your connection can keep up with the process.
Your real phone # is
not revealed unless you have given it out. When making calls from Google Voice, you can use ''hangouts'' and do it from the Computer if you are really not sure about which number will show up. You can test it on a friends phone, or your own, calling the destination number via Hangouts option on Google Voice on PC. When using a web browser, Chrome, Firefox or otherwise, always remember to clear cookies after closing out.
Using programs like CCleaner (C Cleaner) can help rid adware from your computer
and at the same time, remove logs and other important internal files related to your Internet/Computer history that can be tracked.
Lastly, using a VPN helps to remain untraceable, even if a Cop were to 'try' and track your Voice account, if you log-in via an IP address that is secure, then by the time they Subpoena Google for the records, your trace will be long gone. It's all about how you play your cards and the order in which you play them.
