N.Y. Comp. Codes R. & Regs. tit. 7, § 723.6 – Suspension or revocation of inmate telephone call privileges.

(a) Inmates may have their telephone call privileges limited, suspended or revoked pursuant to a disposition of a disciplinary hearing or superintendent's hearing.
(b) Additionally, if during the course of a continuing investigation, the facility superintendent has reason to believe that the safety, security, good order or well-being of the facility or any person is threatened, the superintendent may immediately take action to limit, suspend or revoke an inmate's telephone privileges.
1. (1) In such instances, the superintendent must inform the inmate, in writing, of the underlying basis for the limitation, suspension or revocation, consistent with the need to safeguard the ongoing investigation.
2. (2) The inmate must be afforded an opportunity to respond to the action of the superintendent, usually by a written reply to the superintendent. When the inmate's written reply is received, the superintendent will consider the inmate's comments in deciding whether or not to continue the limitation, suspension or revocation of the inmate' s telephone call privileges.
(c) An inmate may appeal the superintendent's limitation, suspension or revocation of his telephone call privileges in writing to the Deputy Commissioner for Program Services. A response to the appeal must be provided within 30 days of receipt of the appeal in central office.
