Among the GrandCentral features that we have carried over to Google Voice, is the ability to tag a caller as spam.
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.
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.
All things Google Voice!
