Multiple audio stream example
The following diagram shows an intra-realm session with two audio streams. Each stream uses a different codec. Once the session is established, the PCMU count in the show sidp codecs output is 2, and the PCMA count 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 and a single PCMA count will be reflected in each respective query because two m= lines emanate from each realm.
