What should be latency for the VOLTE call to be good MOS?

Question

I kept VOLTE call in mute state, But i can still see an RTP traffic with some payload. Why this traffic is flowing even after call is in MUTE?What is that content of that payload?

Hi,

To be very good MOS score it should be 150ms for application to application.
Average delay in Traditional network is 200 ms. If you exceed this timing then MOS score will be poor.
