Preferred Codec Precedence

When you configure preferred codecs in session agents or realms, be aware that the codec you set for a session agent takes precedence over one you set for a realm. This means that if you set preferred codecs in both configurations, the one you set for the session agent will be used.

In the case where the Oracle® Enterprise Session Border Controller does not find the session agent’s preferred codec in the SDP offer’s media format list, then it does not perform codec reordering even if the media format list contains the realm’s preferred codec.
