Single audio stream example

The following diagram shows an intra-realm session with one audio stream using the PCMU codec. Once the session is established, the PCMU count in the show sidp codecs output is 2.

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 will be reflected in each respective query because only one m= line emanates from each realm.
