How to make calls with Arduino?

I said that I would like the Coolphone to be at least half as durable as the Nokia 3310 and I didn't joke because I will print the case for it from a material called Calibram BT and I will order PCB from PCBWay for this project - link below. Calibram is a high-quality filament containing the best features of several other materials. You can read about it in the link below.
