I know that people have used the Arduino and a cellular shield (such as https://www.sparkfun.com/products/9607
) to send text messages. Would an Arduino be capable of actually making voice calls over a shield?
I've never had a GSM shield myself, so I don't know how much would be done directly on the cellular module or on the Arduino's CPU. Would making voice calls over an Arduino be a feasible project?Please note that I am not trying to create a device comparable to a commercial cellphone.
I saw that someone else created a similar topic a while back (http://arduino.cc/forum/index.php/topic,55455.15.html
) about building a commercial cell phone using an Arduino. My cell phone would not
be a commercial product; it would merely be a novelty for my own personal use, and portability would not be a design goal. (If the device was the size of a lunchbox and didn't even have batteries, I wouldn't care)
Could I do this or is it impossible to use an Arduino as a telephone? If possible, could someone point me in the right direction to get started?
