[Freeswitch-users] Monitoring call quality using variable_rtp_audio_xxx

[Jonathan Hunter]

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
