If you have a Google Voice number, it will appear on the recipient's caller ID. If you haven't set up a Google Voice number, a generic number or the word 'unknown' will appear to the person you're calling.
You understand and agree that Google Voice is an enhanced call-management application and that Google Voice is not capable of making or receiving emergency calls. In addition, if you haven't set up a Google Voice number but you're using Google Voice to call a public-safety answering point (PSAP), then the PSAP will see a generic number or the word 'unknown' on your caller ID and might not be able to call you back.
Google's proprietary rights
Google has the right not to provide calling or connections to any telephone numbers, at its sole discretion. Unserved numbers may include, but are not limited to certain geographical locations, special service numbers, satellite telephony services and other call-forwarding services.
Google Voice provides a function that allows you to record individual telephone conversations. The laws regarding the notice and notification requirements of such recorded conversations vary from state to state. You are responsible for applying the local laws in the relevant jurisdiction when using this feature.
Depending on the Google Voice service that you sign up to, you may be required to pay fees in connection with the Services, as stated by Google. There may be additional fees, if you request a change in any Services. Depending upon the level of Service selected by you, there may be charges for calls to or from certain locations, including, without limitation, payphones and areas within extended calling zones. There may also be applicable charges for any special or enhanced services that you use.
Users may purchase prepaid credit to be used for Google Voice services. Google will be under no obligation to offer any refunds or reimbursement for the purchase price of such prepayment. Use of minutes is billed in one-minute increments. Prepaid credits are billed at the time of purchase.
Unless prohibited by law, any outbound calling credit that you have purchased will expire six months from the most recent date of use and may not be transferred.
Calling credit may be used for calls made using the Service and/or for calls made using the 'Call phone' feature in Hangouts.
Calls made to, and received from, phone numbers in the United States and other countries are routed through, and provided by, various regulated and licensed partners.
The Google Voice service is provided by Google Voice, Inc., a subsidiary of Google Inc.
