Supported Playback Scenarios

This section discusses playback scenarios the Oracle® Enterprise Session Border Controller supports and identifies triggers for playback. When more than one trigger appears, the Oracle® Enterprise Session Border Controller acts on the one closest to the playback endpoint.

These scenarios are defined by the SPL options parameters you configure for realms, session agents, and SIP interfaces. For more information about configuring these options, see Chapter 23, Session Plug-in Language (SPL).

• playback-on-183-to-originator—Playback enabled upon the receipt of a 183 Session Progress destined for the originator and stops when a either a (200-299 or 400-699) final response is sent.
• playback-on-183-from-terminator—Playback enabled upon the receipt of a 183 Session Progress response is received from the terminator and stops when a (200-299 or 400-699) final response is received.
• playback-on-refer—Playback enabled for the caller being transferred when the Oracle® Enterprise Session Border Controller receives a REFER message that is locally terminated (i.e., processed on the Oracle® Enterprise Session Border Controller on REFER completion).
