BOISE, Idaho (AP) — Idaho land-line phone companies contend a 13-year-old law forbidding them from cold-calling existing customers is crippling their ability to market high-speed Internet.

Frontier Communications, headquartered in Minnesota, and Louisiana-based Century Link Inc., are pushing to revamp Idaho’s 2000 law to halt unwanted phone solicitation. The law restricted phone companies from calling existing customers who requested telemarketing peace.
