Note:

Call history, incoming caller ID, and outgoing caller ID are synchronized with consolidated directory contacts . Hence, the name and details displayed in the call history, incoming call screen, and outgoing call screen are from the consolidated directory if the application is not synchronized with the Office 365 account of a user. If the application is synchronized with Office 365, all details in the call history, incoming call screen, and outgoing call screen that are from the consolidated directory are overridden with details from personal contacts in Office 365.
If you have opened the application in multiple tabs in your browser, the call features will be supported only in the first tab you opened. In all other tabs in which you have opened the application, an error message Phone is not available because Mitel One is opened in another tab or window on this device will be displayed and the call features will be disabled.
