This feature is available with the Voice Standard and Premier subscriptions. Learn more

You can set up desk phones to use with Google Voice in your organization. These phones let users make and receive calls over the internet instead of over dedicated telephone lines.

Before you begin

  • Provide power to the phone using a separate power adapter or a PoE (Power over Ethernet) cable.
  • Connect the phone to the internet, either through a wired connection or Wi-Fi. Learn about required network access.
  • Find the MAC address of the phone. It's printed on the back of the phone or shown in the Settings panel on the phone.
  • Make sure users you want to assign to a phone have a Voice license and number.

  • Email address doesn't match a user—This email address doesn't belong to a user in your organization. Change to a valid email address.

Assign a different user to a phone

You can change the Voice number assigned to a phone. If the phone already has an assigned number, you first need to unassign it.

  1. From the desk phone homepage, click the desk phone in the list.
  2. On the left, click Unassign.
  3. At the prompt, click Unassign.
    This removes the previous user from the phone so you can assign it to a new user.
  4. From the desk phone homepage, point to the desk phone you want to update and click Edit Edit.
  5. At Desk phone name, enter a name that identifies the desk phone.
  6. At user name, assign a user to the phone. Enter the first few characters of their name or email address. When you see the name you want, select it.
  7. Click Next.

Supported desk phone models

You can use these models of desk phones with Google Voice:

  • Polycom VVX 150 OBi Edition
  • Polycom VVX 250 OBi Edition
  • Polycom VVX 350 OBi Edition
  • Polycom VVX 450 OBi Edition

If you don't have the OBi Edition models, or you aren't sure, visit Polycom support for details on identifying your model and converting to the OBi Edition Software.

Note: Google Voice for G Suite does not support Obihai devices used with the unmanaged version of Google Voice. You can't connect those devices to your work or school account.

What is a MAC Address?

The MAC address uniquely identifies every networked device, such as a desk phone. The MAC address is globally unique unlike a serial number assigned by the manufacturer.

Note: For Polycom VVX OBi Edition phones, Google Voice supports using the serial number as the MAC address. The only number on the back of a VVX phone is the serial number.
