Another innovation associated with telephone support deals with technologies that identify and filter incoming customer calls. One method is the use of software that attempts to identify the caller (usually based on the incoming phone number) and then automatically directs the call for proper servicing. For instance, an appliance manufacturer may be able to distinguish between those who have purchased a refrigerator and those who purchased microwave oven.
But some marketers go a step further and can program their call routing system to distinguish “good” customers from others. This may result in these customers receiving preferential placement in the calling order or queue so that they will be serviced before lower rated customers who sequentially may have called before the “good” customer.
