How it connects
Portfolio advantageEngage Desktop is the everyday client of Engage PBX, which remains the phone system. It shows who is calling from Command CRM, joins meetings through Fusion Stream, and on Fusion OS is planned as part of Fusion Hub, where a call stays connected when its view is closed.
