How many pins does a Raspberry Pi need to be connected to GSM?
To integrate the rest of needed parts, we created custom 16 pin cable for Raspberry Pi to GSM HAT, since we needed some of other general purpose IO pins to read rotary dial, state of headset switch and to drive bell ring (also to automatically start GSM HAT during power-up / initialization). I tried to use some of off-the-shelf breakout wires for Raspberry Pi for that purpose, and while that worked fine for quickly connecting and testing, I was not very happy with quality, and end up making my own 16 pin connector.

How does a dial wheel work?
When released at the finger stop, the wheel returns to its home position driven by the spring at a speed regulated by a centrifugal governor device. During this return rotation, the dial interrupts the direct electrical current of the telephone line ( local loop) the specific number of times associated with each digit and thereby generates electrical pulses which the telephone exchange decodes into each dialed digit. Each of the ten digits is encoded in sequences to correspond to the number of pulses, so the method is sometimes called decadic dialing .
How are rotary dials arranged?
On the rotary phone dial, the digits are arranged in a circular layout so that a finger wheel may be rotated against spring tension with one finger. Starting from the position of each digit and rotating to the fixed finger stop position, the angle through which the dial is rotated corresponds to the desired digit. Compact telephones with the dial in the handset had all holes equally spaced in the dial, and a spring-loaded finger stop with limited travel.

To dial a number, the user puts a finger in the corresponding finger hole and rotates the dial clockwise until it reaches the finger stop. The user then pulls out the finger, and a spring in the dial returns it to the resting position. For example, if the user dials "6" on a North American phone, electrical contacts operated by a cam on the dial shaft and a pawl will open and close six times as the dial retur…
