The FCC enforces the Telephone Consumer Protection Act. Based upon the TCPA, the FCC has created a number of additional telemarketing regulations in the Code of Federal Regulations. Some of the issues addressed by these telemarketing regulations are:

You must follow whichever rule is more restrictive. For example, the federal rules prohibit telemarketing calls after 9pm, but the state of Mississippi prohibits calls after 8pm.

Many of the FTC and FCC telemarketing restrictions overlap. Your should always follow the most strict rule to ensure compliance.
