I cannot delete a phone on the Mitel 3300. Removed it from Opsman. There was an error message but it no longer appears in Opsman. I cannot delete it from the 3300. Says there is one line in use. I have tried to clear all features. Busy out the exten and return to service. Any ideas. I checked and all of the buttons have nothing assigned to them.
