RSA 359-E:5-a
§ 359-E:5-a. Blocking Prohibited
No person using an automated telephone dialing system or any other method for solicitation in this state shall
use any method, including per-call blocking or per-line blocking, that prevents caller identification
information for the telephone solicitor's lines used to make telephone calls to a residential telephone
subscriber from being shown by a device capable of displaying caller identification information. The caller
identification information displayed shall contain a telephone number at which the telephone solicitor may
receive telephone calls if the telephone solicitor leaves a message on a telephone answering device or uses an
automatic telephone dialing system that plays a recorded message when a connection is completed to a telephone
number.
