Telephony App

You can use the telephony app to make telephone calls. The telephony app starts automatically when you begin a telephone conversation.

The toolbar and other elements are displayed on the telephone's display.

Elements

•

Selection window: The dial window opens when you press the Hook key or the Loudspeaker key, or when the receiver is picked up. In the dial window, you can select the VoIP account and a phone number, or enter them in dial preparation. Additionally, a contact list (internal or external) is displayed from which you can select the subscriber.

•

Business cards: Any data stored in the contacts for a call partner will be displayed on a business card when a call is incoming, during call preparation, and during the call itself. The active business card also contains information about the duration of the call, the account that was used, and any call forwarding that was completed. The business card of a held call shows the name of the call partner, the duration of the call, and the hold duration.

Notes:

The element that is associated with the toolbar is active.

Elements have various outline colours: green for the active element, light blue for an element that requires attention, and grey for an element that is shown only for information purposes.
