Hi all! Could somebody please explain such values in xml_cdr: <rtp_audio_in_raw_bytes>0</rtp_audio_in_raw_bytes> <rtp_audio_in_media_bytes>0</rtp_audio_in_media_bytes> <rtp_audio_in_packet_count>0</rtp_audio_in_packet_count> <rtp_audio_in_media_packet_count>0</rtp_audio_in_media_packet_count> <rtp_audio_in_skip_packet_count>44837</rtp_audio_in_skip_packet_count> <rtp_audio_in_jitter_packet_count>44759</rtp_audio_in_jitter_packet_count> <rtp_audio_in_dtmf_packet_count>0</rtp_audio_in_dtmf_packet_count> <rtp_audio_in_cng_packet_count>0</rtp_audio_in_cng_packet_count> <rtp_audio_in_flush_packet_count>0</rtp_audio_in_flush_packet_count> <rtp_audio_in_largest_jb_size>0</rtp_audio_in_largest_jb_size> <rtp_audio_in_jitter_min_variance>30.77</rtp_audio_in_jitter_min_variance> <rtp_audio_in_jitter_max_variance>400.00</rtp_audio_in_jitter_max_variance> <rtp_audio_in_jitter_loss_rate>1.37</rtp_audio_in_jitter_loss_rate> <rtp_audio_in_jitter_burst_rate>0.37</rtp_audio_in_jitter_burst_rate> <rtp_audio_in_mean_interval>20.00</rtp_audio_in_mean_interval> <rtp_audio_in_flaw_total>3</rtp_audio_in_flaw_total> <rtp_audio_in_quality_percentage>99.00</rtp_audio_in_quality_percentage> <rtp_audio_in_mos>4.49</rtp_audio_in_mos> I believe that this means that FS actually receiving packets from the client but drop them all by some reason. Incorrect configuration of the jitter buffer?
