    I am working on application that using dylib,application is working on background all the time,
    so I would like to send DTMF tones during the call.
    there are some function in core telephoney like CTDTMFPlayStart, CTStartDtmfTone,
    but I don't how to use them really.

    I would appreciate any help, hint for sending DTMF tones during the call.
