Hello to all, I have some questions, I'm using Wireshark to study the Parameters of Quality of Service for VoIP. I use the option in statistics called "RTP" and then "Show all Streams" my doubt is that I´m confused with some terms.
- Max Delta
- Max Jitter
- Mean Jitter
I´ve read that :
• Delay. When packet delay approaches 150ms, voice quality becomes difficult.
• Jitter must be less than 60ms for minimum voice quality or less than 20ms for toll quality. Other authors believe that Average one-way jitter should be targeted at less than 30 ms.
In Wireshark the Max Delta represents the DELAY?, are these concepts all right? and if Max Jitter is < 30ms is acceptable?
Thanks for your time....
Sincerely yours,
Andreina
