ITU-T to IANA Codec Mapping
The Oracle® Enterprise Session Border Controller maintains a list of ITU-T (H.245) codecs that map to IANA RTP codecs. An ITU codec is directly mapped to an IANA Encoding Name for media profile lookups. All codecs are normalized to IANA codec names before any matches are made. New ITU-T codecs can not be added to the media profiles list.
The following table defines the ITU-T to IANA codec mappings.
