Hi Quang, Unfortunately the call quality settings in VoIP metrics report block hasn't provided call quality calculation, currently it only provides API to set call quality values from external calculation, see pjmedia_rtcp_xr_update_info(). Any contributions on this will be greatly appreciated :) Moreover, report blocks containing RLE (or per packet analysis) are not supported, thus only last four reports block are supported (with a note as mentioned above).
