Since Opus is a variable bandwidth codec, i don't have a concrete answer.
When I asked around before regarding bandwidth needed for WebRTC connections from home, I got:
The bandwidth requirements are almost the same as the bandwidth requirement for opus and vp8. Real time audio typically has a bitrate of 40-200kbit/s. Video requires at least 200 kbit/s (500kbit/s if you want to see people's faces).
According to webrtc-experiment the minimum bandwidth for opus is 6kbit/s and for vp8 100kbits/s. So in total that makes 106kbit/s but when you account for the overhead of the webrtc protocol stack and constantly varying network conditions I would guess that 200kbit/s is the minimum if one wants stable video and audio.
Chrome and Firefox both use opus and vp8 so the bandwidth requirements should be the same. Although I don't have any hard data to prove it.
You can see the current traffic generated by webrtc by going to chrome://webrtc-internals and inspecting all the charts

George, thanks for your response.., We will be enabling our Agents with Auto Answer, with a Whisper. What if any overhead will there be with having the connection set as persistent.. Thanks

If you use auto-answer to get the calls connected to the agents as quickly as possible, then setting the WebRTC phones to persistent is definitely recommended to cut down on the amount of time it takes to actually get the call connected to the agent.

Hi
Please can you clear me. I do not sure if the persistent connection must be activated in the webrtc configuration.
What is the recommendation, activate the persistent connection or not?
Thanks for your answer
