Hello!

It actually specifies the preferences of the sender of the description.
Yes, this is what I understand.
This allows the sender of the media to switch between codecs depending
on network conditions, i.e. you might prefer ISAC to Opus in some
scenarios. Modern codecs like opus do this inband.
But I don't understand how? How this information can help?
Ok, let's suppose responder knows, that initiator preferes Opus, then
Speex, then ISAC and initiator knows that responder preferes Speex, then
G.722, then Opus.
Now, how this information can help them to switch between codecs
depending on network conditions?
With my best regards,
Konstantin
