But there are two things I'd like to understand, first: a) how did Mer people solve this? Or did they just ship nokia binaries? b) do we really need those DSP algorithms? Can we just take data from microphone and send it down the GSM line, and take data from GSM line and put it to the speaker? If it will not work in the speakerphone mode, I can live with that... It should somehow work in normal-phone mode, and be definitely feasible with wired handsfree, no?
