Ok i took an older telephone took off the handset and coily cord. THen i spliced a 2.5mm jack onto the coily cord. Next i removed most of the innards of the headset and replaced the microphone with an small microphne type thing (i ripped it out of a furby), then i replaced the speaker with a small earbud type one. Then i tested it on only of my cordless phones at my house, the speaker output was a little quiet but fine. Now for the problem and real reason i made it the cellular phone. When i plug it in and having a conversation i cannot hear what the other people are saying at all, but they can hear me fine. Can anyone provide insight to why its doing this and also a solution to the problem

what specific transistor should i use? and amplifying the voltage would cause to common's voltage to be higher too, could that hurt the cellular telephone?

your going to need to amp it up theres lots of ways to do this. you could use a audio transfromer or a transistor to name a few

Check the speaker connection of the cell phone with a scope and make sure your signal is strong enough.
