From there, on the left side under “ADMIN“, click the dropdown “Phone System Management“ and click “Company Info“. Then, click on “Account Settings“ at the stop of the page.
Under the “Settings“ tab, click on “Desk Phone“. Make sure that the “Web Interface“ toggle is enabled. While you are here, make note of your Admin Passcode. If you are trying to get back into the phone’s GUI, the password was changed to the one displayed here.
I hope that anyone provisioning their physical phone to Zoom Phone can use this tip to help them access the GUI.
