Certificates will be issued defining certificated areas, and no further authority to construct, extend or enlarge telephone facilities within said certificated areas need be obtained from the Commission by the certificate holder, but certificates may be amended by proper application to extend or enlarge a certificated area. Any other person, however, shall not, under penalty provided by law, construct, operate, acquire or own any telephone facilities, lines, plant or system within an area certificated to another without authority from the Commission.
