If neither the required telephone number or facsimile machine number is a toll-free number, a separate cost-free mechanism including a website address or email address, for a recipient to transmit a request pursuant to such notice to the sender of the message shall also be provided. A local telephone number also shall constitute a cost-free mechanism so long as recipients are local and will not incur any long distance or other separate charges for calls made to such number. The telephone and facsimile numbers and cost-free mechanism identified in the notice must permit an individual or business to make a request to prevent the transmission of future unsolicited advertisements twenty-four hours a day, seven days a week.
