    I updated the firmware.
    Do not have this issue anymore.

    but i realised, when i use the same network Wifi.. its can speak and hear from the camera.
    When using outside network like 4G network.. or other internet, cannot even receive or send the voice to the camera.

    Please fix this issue.!
