What's INWATS? An easier way for out-of-town customers to place their business with you! INWATS stands for Inward Wide Area Telephone Service. It lets selected customers call your company Long Distance with no cost to them. INWATS provides you with incoming telephone service from areas which you have selected. It automatically reverses the Long Distance charges so that you, instead of your customer, pay the toll. New, advanced telephone switching equipment makes sure only calls from these preselected areas are accepted toll-free. This service will increase the incentive of your present customers to do more business with you, and will help attract new customers, too. For details about how INWATS can serve you, call the Michigan Bell Business Office and ask for a Communications Consultant. Michigan Bell - Part of the Nationwide Bell System
