if the debt collector knows the consumer is represented by an attorney with respect to such debt and has knowledge of, or can readily ascertain, such attorney’s name and address, unless the attorney fails to respond within a reasonable period of time to a communication from the debt collector or unless the attorney consents to direct communication with the consumer; or
