Final answer:
The TCPA restricts solicitations that are delivered via voice telephone calls, not email, fax, or any other form of communication.

This means that the TCPA regulates unsolicited telemarketing calls made to consumers. It does not apply to solicitations delivered through email, fax, or any other form of communication.
