Local Media Playback

Commonly, ringback is the media playback of a certain tone informing callers their calls are in progress. In typical deployments, remote endpoints or media servers handle ringback generation, leaving the Oracle® Enterprise Session Border Controller to proxy RTP. When endpoints or media servers do not support ringback generation, the Oracle® Enterprise Session Border Controller becomes responsible for producing it.

Note:

The Oracle® Enterprise Session Border Controller supports a maximum of 100 simultaneous playbacks.

You can configure the Oracle® Enterprise Session Border Controller to generate ringback locally, meaning it can produce RTP media on a media flow. The most common use for enabling the system to produce RTP on a media flow is to support locally generated ringback. Since you can also use this capability for music-on-hold, announcements, and interrupting media for notifications, this Oracle® Enterprise Session Border Controller capability is referred to as local playback.

Local playback is controlled through the ACLI using the Local Media Playback SPL configuration. For more information about SPLs, and configuring the Local Media Playback SPL Plug-in, see Chapter 23, Session Plug-in Language (SPL).
