The term, gross receipts, as used in this chapter, includes only revenue of a telecommunications company from the sale at retail of intrastate and interstate telecommunications services. Sale at retail does not include special access or toll-free incoming calls or the sale of any telecommunications service by a telecommunications company to another telecommunications company if the service is resold or becomes a component part of the sale by the second telecommunications company. Any hospital, hotel, motel, or place that provides temporary accommodations selling telecommunications services to its patients or guests is not a telecommunications company for the purposes of this chapter.
