Interesting. I don't think I've ever come across a softphone that does 
such a thing. Do you have a specific implementation in mind? Is this the 
one that MCG was referring to?

MCG, picking a default bitrate is not a simple matter, which is why many 
implementations allow you to play with it. You may want to try this.

Some could potentially be adapting it based on RTCP feedback but I don't 
think any of the current Opus supporting applications do this.

Cheers,
Emil
