The signing process for hot desking users using Poly Edge E devices is simpler. The NFC technology allows you to sign in to those devices with a simple tap on your mobile app.
If a desk phone has hot desking enabled, you can temporarily sign in to the phone. When you sign out, the phone will be re-assigned to the original owner or reverted to a common area phone. Typically, you'll see Unassigned on the home screen of common area phones.
Note: Admins can set a session timeout limit for hot desking. When the limit is reached, the phone will automatically sign out of the hot desking session.
