Dear All,

        I am forming a WIFI VOIP networks as follows:

        WIFI phone <--- wifi ---> AP (madwifi)+WDS <--- wifi ---> WDS+AP(madwifi) <---wifi ---> wifi phone
                                Router 1                                            Router2 connecting IPPBX
        This setup is outdoor environment testing range and performance of WIFI for VOIP.
        The observations are voice clipping for long distance call and voice cut when in motion.
        What parameters need to be tuned to make long distance calls a success with good quality voice.
