Assigning a device to a phone user (admin)

After purchasing a Zoom Phone HaaS device, it will be automatically provisioned to the account. It will appear as an unassigned device in the web portal.

There are three ways to assign the device to a phone user:


  • HaaS devices will use the default display name for desk phone (Desk Phone).
  • HaaS devices will have a (HaaS) label after the display name for easy identification.
  • If you have multiple sites, the devices will belong to the site they were shipped to.
  • If the phone user belongs to a different site than the original site, the device will be moved to the same site as the phone user.
  • You can't manually remove HaaS devices from the Zoom web portal.
