Before you begin

You have to add users to your organization in Cisco Webex Control Hub before you can add a device to them. See Add Users Manually in Cisco Webex Control Hub.
  • If you're adding an Analog Telephone Adapter (ATA) with more than one port, each port is treated as a separate device in Cisco Webex Control Hub.

  • If you want to add a Cisco desk phone, your organization requires a Cisco Webex subscription that includes calling.

  • Desk phones and analog telephone adapters can be assigned to a user. Room Devices must be assigned to a place. See Add Shared Devices to a Place for more information.

  • If you're adding an ATA, you must configure all network settings before activating the device.

    After you activate the device, you can't access or change these network settings. Here are a few examples of available network settings: VLAN, IP address, and subnet mask.


From the customer view in, go to Devices, and then select New Device.


Select Existing User, and then select Next.


Start typing the username in the drop-down list, choose the right user you want to add a device to, and then select Next.


Use the QR code or 16-digit code to activate the device.
