It’s always hard to keep track of so many different phone numbers, and so many different voicemails, But Google is here to help. The company unveiled yesterday a new service that will give customers one number for all their phones, and will even e-mail their voice messages for them.

After Google’s acquisition of GrandCentral in July 2007, everyone was left with a bit of bitter taste and question on what is going to happen to the service. Well, Google didn’t forget about it, and is now challenging rivals with Google Voice, a new service that will open as soon as possible.

The service will be available at first for GrandCentral users, and it will later be available for new users as well. But it’s the new features that are the most exciting, namely the Voicemail transcript capability, which is still rough around the edges, but should be perfected soon.

Google will make it easier for people to manage their voicemail, by simply archiving these messages, and making them available in the central voicemail inbox. This inbox can be accessed from the Web, and will make message search faster and easier.

The service will become available to GrandCentral users over the next couple of days, when they should receive instructions in their inbox about how to start using the new Google Voice. The service is free of charge, and offers everything from one number for all the user’s phones, to easily manageable voicemail, enhanced calling features such as call blocking and screening, voicemail transcripts, call conferencing, international calls and more.
