TOWA Phone

Some days ago, when i was scrounging through the closet i’ve found an old rotary dialer telephone. These kind of telephone cannot be used nowdays due to incompatibility between pulse and tone dialing. My aim was to replay old feelings: classical ringing sound, rotating dialer and a heavy comfortable handset. Then i decided to relive that and so, in this instructables, i’ll show how to transform a rotary dialer telephone to GSM telephone using Arduino and a SIM900 GSM shield. From late 60’s till 1985, the only Italian telephone company (SIP) furnished to each contract subscriber a basic rotary dialer telephone Siemens AUSO brand named “bigrigio”, that translated means “double-grey”. Expensive calls and slow number dialing didn’t help to people communications like today.”
