Best settings for Opus

Hi,

I’m currently testing out Opus codec. I intentionally throttled my bandwidth but the quality and bandwidth consumption didn’t self adjust for the packet loss.

What are the best settings for codecs.conf so that it can do what it was designed for and handle packet loss and self adjust the bandwidth usage?

Thank you very much

Using asterisk 13 with pjsip and tested with Bria and Grandstream.
