How to Replace AT&T Voice Mail With Google Voice
Google Voice's primary service provides a new phone number to which you forward calls from multiple other lines, including your home phone and cell phone. If you want to use Google Voice as a replacement only for your AT&T mobile voice mail, you can instead use Google Voice Lite. This service stores phone messages in your Google account in place of using AT&T's dial-in or visual voice mail. If you already have a Google Voice number, you can add your AT&T phone's number to your account to merge its voice mail into your Voice mailbox.

- To return to AT&T's default voice mail, remove your phone number from the Google Voice settings page and then dial "##004#" from your phone.
