Set up desk phones

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

Set up desk phones to use with Google Voice in your organization. That way, your users can make and receive calls over the internet, instead of over dedicated telephone lines.

Before you begin

  • Provide power to the phone through a separate power adapter or a Power over Ethernet (PoE) cable.
  • Connect the phone to the internet through a wired connection or Wi-Fi.
  • Each user that you want to assign a phone to must have a Voice license and number.
  • Find the Media Access Control (MAC) address of the phone. It's printed on the back of the phone or shown in the settings panel on the phone.

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.
