I want to encode data via a DTMF encoder and send it back to the iPhone via the 3.5mm Jack. Is it possible to send data back into the 3.5mm jack. conventionally audio signals are sent out over the iPhone 3.5mm jack?

Is there provision to deal with DTMF and 3.5mm jack based input applications in Iphone's External Accessory framework?
