ABSTRACT:
An enhanced "800" service automatically provides a second communications path between a customer and a business in order to provide additional product information, such as video information, to the customer. For example, upon receipt of a customer telephone call on a B-channel of an ISDN facility, premise switching equipment, of the business, automatically receives the customer's network address. This address is used to automatically setup the second communications path to the customer.
