    Hi

    Should use Class CMdaAudioRecorderUtility and SetAudioDeviceMode(ETelephonyMixed) after that you can record
    voice from phone call

    AFAIK the SetAudioDeviceMode() implementation is broken and it really doesn't matter how you set it. At least that seems to be case with 6.1 OS.

    Re: Streaming voice from a call

    Hi all,

    Does anyone know can CMdaAudioInputStream be used to record audio while there's an active call?

    Coz I've tried this and it gave error -13

    I want to use this to detect dtmf, that's why I may not use CMdaAudioRecorderUtility because it will be not real time

    And, if CMdaAudioInputStream can't be used during a call, then do you know the solution? Mine is :
    using CMdaAudioRecorderUtility, record per 1 second and analyze the data until it found a DTMF, but I think the reaction will be quite slow

    Or, is anyone know how to detect dtmf in a call?


    thanx in advanced

    Have you tried editing the Call Recorder Example?
