A sponsor may offer a caller the means to bypass the preamble on subsequent calls, provided that the caller is in sole control of that capability, except that any bypass device shall be disabled for a period of 30 days following the effective date of a price increase for the pay-per-call service. A sponsor shall include at the end of the preamble or the end of the program instructions on how to bypass. (Added 1993, No. 99, § 2.)
