To reuse a phone already assigned to one Webex Calling user or workspace for another, the admin follows a reassignment procedure that includes deleting the device and factory resetting it if it was not already reset, after which the phone shows the Activation Code screen.

Checked 2026-09-25

If the device was not factory reset already, only then you must factory reset the device.
