Codecs
Press this to display the codecs in the sequence in which they are used.
If you select a codec, you can replace it with a different codec, or none at all.
To achieve the best possible balance between bandwidth and speech quality, we recommend you do not change the sequence of the codecs.
Note: Codecs that are assigned multiple times are automatically removed from the list and replaced with
---.
