How to make a handset for your mobile phone.

Resubmit the old guide who had retired to connection problems, of course, this updated guide has eliminated these problems and remains accessible to all users, or nearly so.

Note, the pictures of the old guide those persons using a mono plug, so take them only as a reference.

Material:
An old home phone handset.
A stereo plug 4-pin 3.5 mm or 2.5 mm (depending on your mobile).

Step 1

Cut the phone connector on the side that connects to the phone and not on the side of the handset. Usually this side is + long.

Nice Job
But an stereo jack has only 3 contact pins I think
Could you tell us where you did find your 4pin connector?

is necessary 4-pin because there is a microphone. In Italy I find in all the electronic hardware stores. However, there is on Ebay :-)
