RE: Mitel 5320 locked & how to unlock Billz66 (TechnicalUser) 24 Sep 20 21:06 i agree - helps to know from the start what you are using most likely they are device only extensions and are waiting for a real user to log into them other than that i can only think they might have been pin locked - havent used that for so long , i cant remember whether that shows anything on the screen If I never did anything I'd never done before , I'd never do anything.....

This can mean two things - 1) Phone is set for hotdesking in the Class of Service. You will need to login as a Hotdesk user 2) The phone's Service Level is set as a Multi-device Service Level assigned to it and you have not associated the phone to a MDUG (multi device User Group).
