circuit interface between headphone output and mic input

[mogiz]

I search for a circuit that can transform headphone output of one mobile to the mic input for another mobile


also i ask if i can make a direct connection from wires of headphone to the wires of micphone for another mobile

thank you

Microphone input have just an higher impedance than standard line input.

So, 'high' voltages might burn input of the controller IC.
