The calling mode in Salesforce, and majority of our supported apps only usually allow to them to select either 'RingCentral App, RingCentral Phone, Browser, and RingOut'.

The RingOut is usually a workaround, however, is depends strictly on the user's call handling settings which may cause their app to ring. If we could have the option to select Deskphone wherein they won't be interrupted by their RingCentral app it would benefit a lot of users especially people who use CRMs for Sales are accustomed to using their deskphone.
