Instructions:
You need two phones, one as a
receiver (phone_1), the other one as a transmitter (phone_2); mobile phone_1
connected by DTMF audio cable 3.5MM audio controller (the controller to be
powered), and then using phone_2 ( may be a fixed telephone) call the phone_1, phone_1
answered, so that two phone call each other; then dial 1/2/3/4/5/6/7/8 by phone_2
