A more thorough explanation:

Definition: Oregon has laws in place to regulate telemarketing and telephonic anti-solicitation, as well as fax anti-solicitation. These laws are designed to protect consumers from unwanted and potentially fraudulent phone calls and faxes.

• Telemarketing and telephonic anti-solicitation: Oregon law prohibits telemarketers from calling consumers who have registered their phone numbers on the National Do Not Call Registry. Telemarketers must also identify themselves and the purpose of their call, and must not use false or misleading information to try to sell products or services.
• Fax anti-solicitation: Oregon law prohibits unsolicited faxes that advertise or promote goods or services. Faxes must also include a notice that allows the recipient to opt-out of future faxes.

These examples illustrate how Oregon's laws aim to protect consumers from unwanted and potentially fraudulent phone calls and faxes. By requiring telemarketers to identify themselves and the purpose of their call, and by prohibiting the use of false or misleading information, consumers are better able to make informed decisions about whether to engage with the telemarketer. Similarly, by prohibiting unsolicited faxes and requiring opt-out notices, consumers are able to avoid receiving unwanted advertisements and promotions.
