The Core Instance is a grouping of applications to aide in call tracking and delivering the defined caller experience in Callback.
At least one Core Instance is required in a Callback solution. A seconds Core Instance can be deployed. A single Core Instance in a Callback solutions is typically referred to as a Standalone solution.
