I would like to make a program to make and receive calls.
The project is as follows, a vintage dial telephone with rotary, an arduino, a gsm card that goes with it, and I would like to be able to make and receive calls.
The arduino and the gsm card will have to discuss together for the management of the line to make and receive calls.
I only need the soft part, I take care of the wiring and the hardware.
reference of the arduino and gsm card on request
Looking for quotes
