DIY Arduino Cellphone

Yes, it's true. A complete mobile phone with Arduino heart.
David has created a basic phone, which can make and receive calls and text messages, store numbers, names and display time.
He has used an Arduino GSM shield and a few more components, and has two variants: one with an array of LEDs and one with an LCD.
On their website are available schemes and programs needed for yourself can make this super-style brick Nokia!!

Arduino Doorbell Phone

Ring a phone and create a wireless doorbell with an Arduino.

Bryan gives step-by-step instructions of how he converted a 1940's Swedish-made Ericsson bakelite original into a wireless doorbell...

This project combines a battery-operated doorbell, antique phone, Arduino, and subscriber line interface circuit (SLIC) to make a wireless doorbell. The Arduino project include phone restoration, creation of a custom doorbell button transmitter, modification of the receiver, workings of the SLIC, and description of the Arduino code. A 'Retro' hack project will be of interest to people who like to repurpose antiques.
