flaws are missing or out-of-order packets. If you get subsequent missing packets it counts as 2 flaws. The number of flaws out of the total number of packets is the quality percentage. The quality percentage rounded to a scale of 4.5 is the mos. On Tue, Jun 6, 2017 at 1:59 AM, Jonathan Hunter <hunterj91@hotmail.com> wrote:
Hi Guys,
To be more specific, what is the meaning of this parameter?
in_flaw_total
I am becoming clear on the other parameters!
Thanks
Jon

Hi Guys,
Sorry for the noise, we are looking to poll calls in progress to grab the rtp_audio variables when a call is in progress, and we want to understand if this is a good approach and to that end what values/variables we should consider and what ranges should we be working with?
I understand mos and quality percentage but what other values are a good indicator?
Again Im clear on jitter and its meaning just want to understand whats what as not everything understandably is not documented.
Many thanks
Jon
