Transcoded audio stream example
The following diagram shows an intra-realm transcoding scenario where the originator and terminator are using different audio codecs. The Oracle® Enterprise Session Border Controller transcodes the media, which is invisible to the endpoints. Once the session is established, the PCMU count in the show sidp codecs output is 1, and the PCMA count is 1.
If the session originator and terminator in the previous diagram exist in two different realms, you must execute the show sidp codecs command twice, once for each realm. A single PCMU count appears in one query and a single PCMA count appears in the other query because only one m= line emanate from each realm.
An example show sipd codecs <realm ID> command follows:
ORACLE# show sipd codecs net172
09:20:04-30 Realm net172
