RTP Payload Type Mapping

The Oracle® Enterprise Session Border Controller maintains a default list of RTP payload types mapped to textual encoding names as defined in RFC 3551.

The following table defines the preconfigured payload type for standard encodings.

Payload Type Encoding Name Audio (A) / Video (V) Clock Rate
0 PCMU A 8000
4 G723 A 8000
8 PCMA A 8000
9 G722 A 8000
15 G728 A 8000
18 G729 A 8000

If you configure any payload type to encoding name mappings, the default mappings will be ignored. You must then manually enter all payload type mappings you use in the media-profile configuration element.
