We are writing to express concerns about the FCC Declaratory Ruling and Final Ruling of July 10, 2015 regarding the Telephone Consumer Protection Act (TCPA) that addresses autodialing to cell-phones. We are concerned about the effect of the ruling on the population sciences and respectfully ask the Federal Communications Commission (FCC) to consider issuing an exemption covering cell phone use in scientific research.#GPAC2015#LettersandComments
