Software-based transcoding

The Oracle Communications Session Border Controller supports media transcoding on virtual platforms. Refer to the Transcoding Support section of the Release Notes for the list of codecs which may be transcoded with software-based transcoding resources.

Transcoding is the process of converting voice audio streams from one encoding format (codec) to another. In addition to conversion between codecs, the Oracle Communications Session Border Controller can also reframe compressed audio streams from one packet size to another (e.g. 10ms G.729 reframed to 30ms G.729) according to packetization times specified in session establishment. The Oracle Communications Session Border Controller may then convert between any supported codecs and frame size combination to another supported codec and frame size combination.

Software-based transcoding is configured identically to hardware-based transcoding, and is invoked when codec policies are configured but no transcoding hardware is recognized in the system.
