Resale of service.

1. Except as otherwise provided in subsection 2 or as otherwise ordered by the Commission, no telephone company which provides a customer with intrastate long-distance telephone service may prohibit the customer from reselling or sharing that service, but the company may require the customer to subscribe to sufficient lines to avoid any blockages within the company’s system which might adversely affect any of its other customers. 2. The provisions of this section do not apply to a competitive supplier.
