How to determine the quality of WebRTC call

Here is the stats report info that I got from the Peerconnection jingle library in Android.

I want to display an indicator on the UI to show the user the current call quality based on this report if possible.

I'm not sure how to determine if it is a good call quality or bad quality

I would recommend showing them the basic stats to the user as a first step like Packet loss %, bandwidth (upload & download), if possible the network signal strength. Calculate them for every two seconds.

Ref:

Chromes Webrtc stats: chrome://webrtc-internals

Signal strength: How to detect internet speed in JavaScript?

Packet loss: Math.round((totalPacketLost / totalPacketSent) * 1000);
