As of Polycom UC Software 3.3.0, you can configure a simplified set of codec properties for all phone
models to improve consistency and reduce workload on the phones. Phone codec preferences are listed
in the table Voice Codec Preferences Parameters.
If a particular phone does not support a codec, the phone will ignore that codec and continue to the codec
next in the priority.
For more information on codecs on particular phones and priorities, see Audio Codecs.
