PC World — After weeks of anticipation, Google is finally accepting a limited number of new users into its Google Voice phone system. Google Voice allows you to unite all of your phones under a single number and then use a powerful set of controls to determine how calls are handled. It packs plenty of other impressive functionality, too, including voicemail-to-text transcribing and advanced call-screening.

At the same time, though, adopting Google Voice as your communications commander introduces some potential negatives, ranging from privacy-related concerns to questions about reliability. Here's a breakdown of five pros and five cons to help you determine whether the service is right for you.

Google Voice: 5 Reasons to Use It

1. Routing power

Google Voice eliminates the problem of having multiple numbers for multiple purposes. Once you sign up and receive a phone number, you input all of your existing numbers--your cell phone, work phone, home phone, and anything else--into the control panel. Then, when you receive a call, all of your phones will ring (or a smaller subset, if you choose), and you can answer on whichever one is most convenient at the time.

The true power, though, comes with Google Voice's advanced routing options. You can set your preferences so that certain calls will ring only certain phones. If, for example, you wanted your spouse's calls to go straight through to your cell phone, or your mother's calls to ring only on your home phone, you could make those specifications. You could even set certain callers to be routed directly into your voicemail.

2. Screening power

Once a call comes through, you have a whole new set of options. When you pick up the call, and while the caller still hears ringing, you'll be presented with the person's name and four options: answer the call, send it to voicemail, send it to voicemail and listen in live, or answer and record the call.

Google Voice uses information from your address book to tell you who's calling. If the caller isn't in your contacts list, Google Voice can ask for their name and play it back for you when you pick up.

3. Voicemail power

As mentioned above, Google Voice's voicemail system allows you to listen in while someone is recording a message. If you decide to pick up midmessage, you simply press the star key and begin talking.

Google Voice's voicemail is fully accessible over the Web, too: You can listen to voicemail online, forward voice messages to other users, and even embed them on other Web sites. Google Voice also offers text transcriptions of your voice messages and the ability to receive them via e-mail or text message.
