Google Voice Blog

Among the GrandCentral features that we have carried over to Google Voice, is the ability to tag a caller as spam. This means that future calls from that number will not ring your phones, will not be in your messages when you check voicemails from your phone, but will end up in a Spam folder that you can check whenever you feel like it, similar to your Gmail spam filter. Tagging a caller as spam only affects your account and is not shared with other users.

One of the lesser known features of the Phone Spam filter is that we also collect numbers from reported (and confirmed) Phone spammers to block them for the benefit of all our users (we call it Craig's list internally since Craig came up with that idea).

We have received several questions about what happens to GrandCentral accounts after upgrading to Google Voice.

Although no new call/voicemail will show up in the GrandCentral account, you can keep accessing your GrandCentral voicemails, call log and address book even after you have upgraded.

Note that you can export your GrandCentral address book and import it in your Google address book if you don't already have them there.

Hello GrandCentral (and soon to be Google Voice) users:

We have started the upgrade process, and are rolling the service out to new users on an ongoing basis. When your account is ready to upgrade, you will notice an "Upgrade" message at the top of your GrandCentral inbox.
