[Freeswitch-users] Identify voice quality issues using CDR records

[sukitha jayasinghe]

Dear all,

I have serious voice quality issues in my freeswitch 1.6.20 installation.
In CDRs I found that the voice quality percentage is 100 and mos is 4.5,
but the quality is very bad for one side. I have pasted the audio part of
the CDR below. What mean by the skip packet count. Is it possible to
identify the issue by looking at these statistics?

"audio" : {
            "inbound" : {
                "raw_bytes" : 90298,
                "media_bytes" : 90298,
                "packet_count" : 1235,
                "media_packet_count" : 1235,
                "skip_packet_count" : 1184,
                "jitter_packet_count" : 0,
                "dtmf_packet_count" : 0,
                "cng_packet_count" : 0,
                "flush_packet_count" : 0,
                "largest_jb_size" : 0,
                "jitter_min_variance" : 137.097046,
                "jitter_max_variance" : 315.2,
                "jitter_loss_rate" : 0,
                "jitter_burst_rate" : 0,
                "mean_interval" : 27.274788,
                "flaw_total" : 0,
                "quality_percentage" : 100,
                "mos" : 4.5
            },
