Only Office Admins can purchase Obihais. They can set them up for their own account, for other users, for Main lines or Departments, or assign them as room phones for general team use.
To purchase a phone for a team member, navigate to Office>Team>Buy Desk Phones.
From the Obihai purchase page, enter your device quantity and confirm your purchase.
