converting a telephone into a microphone

the EXACT frequency response is this: 300hz-3400hz, and the frequency bandwidth is controlled by the phone co.'s electrics. the curve peaks +40db at 347hz and drops exponentially to about +19db at 3400hz. that is some shitty charachteristics. i got the info from this telecommunication and lightwave relay systems class i took in pursuit of my EE degree, which i will be going to msoe next year....that means only 2 more years!
