How Google Voice Works (2024)

Google Voiceis a telephone service that can unify communication channels so that several phones can ring simultaneously via one single, free phone number that works like most other phone numbers. Upon an incoming call, you have several options to handle this communication.

At its core, Google Voice is not a VoIPservice likeSkype, but it does take advantage ofVoIP technologyover the internet in order to route some of its calls, to allow international calls at a cheap rate, to allow free local calls, and to offer the numerous features it's known for.

Google Voice provides a phone number. With it, incoming calls forward to any phone of your choosing—your house phone, smartphone, or another phone.

Another way to use Google Voice is to port your primary phone number over to this service, to use your existing number as your Google number, but this feature has a few caveats.

How Google Voice Works

Google Voice links with the PSTN—the wired landline telephone system—and the mobile network to hand over the calls. Any call initiated through it necessarily has to pass through the PSTN. However, the PSTN doesn’t do all the work. The call is then handed to Google's servers, which is where the numbers are pooled.

Say, for example, the call is directed to another Google Voice number. That number is identified within Google’s numbers, and from there, the call is sent to its final destination.

The main aim of Google Voice is to unify communication channels rather than saving on cost. As a result, you can easily switch carriers without having to change the phone number, because one number can ring any phone through any carrier. If your physical phone number changes, all you need to change is the number to which your calls are routed.

7. Select Verify to confirm that the code has been entered correctly.

8. Choose Claim to confirm you want to forward Google Voice calls to that phone number.

   If Google Voice is already forwarding calls to that phone, setting up a new Google Voice number with that phone removes it from being used with the previous Google Voice number (i.e. calls that used to be forwarded to your phone from another Google Voice account stop ringing that phone). This glitch only happens if you've used the same phone with another Google Voice number from a different Google account.

9. Use the Finish button to finish setting up Google Voice then click Finish again on the final screen to open your Google Voice account.

Ringing Multiple Phones

Your Google Voice account supports several configuration settings and preferences, among which is a feature that allows you to set which phones you want to ring when someone calls your Google number. You can enter up to six different numbers to have six different phones or devices ring upon a call. For example, you may have your mobile phone, home phone, and office phone ring.

Here's how to set up multiple phones with Google Voice:

1. Open your Google Voice settings from the three-dotted menu button on the left side of the Google Voice website.

   

2. With the Phone numbers tab selected, locate the Linked numbers section of the settings.

3. Click or tap New linked number under your existing phone number.

   

4. Enter the phone number that should accept Google Voice calls, and select Send Code, or Call if you chose the phone call option.

   If you chose the calling option, you have to click or tap Call once more to start the phone call.

5. In the space provided on the Google Voice website, enter the code you received over text or heard over the phone call.

6. Return to the Google Voice settings page from step 1 and open the Calls tab.

7. Make sure there's a check in the box next to all the relevant phone numbers. If there isn't, put a check in the box next to each number that should ring when a call comes through your Google Voice number.

Other Features of Google Voice

Along with making and receiving phone calls, Google Voice has several options that let you customize what happens when someone tries to reach you. You can set rules for both individual contacts and groups of them that will forward their calls to another number (for example, your home phone), send them directly to voicemail, or only put them through to specific devices. Other options let you screen calls and use customized greetings for specific people.

Google Voice Cost

Google Voice is not a complete alternative to the services of cell phone carriers, unlikeSkype and the like. However, while you still have to pay your phone or wireless carrier in order to use Google Voice (since it has to connect to your phone to be used), it's still free, meaning that you don't have to pay anything extra to use Google Voice.

Google Voice does allow you to save money, though:

• Make free local calls and overseas calls (inbound from outside the US) to any number within the United States and Canada.
• Place cheap calls (at VoIP rates) to any international destination. Such calls would be many times more expensive through PTSN telephony.
• Google Voice offers free SMS so that you can send text messages through your Google number without paying.
