Smart Transcoding: If the SBC (Enterprise or Access SBC) detects WAN network
impairments during a call between the Enterprise SBC and Access SBC, the SBC
employs voice transcoding by switching the coder from G.711 to Opus for that specific
call only. Transcoding is done only on the path between the Enterprise SBC and
Access SBC. As Smart Transcoding is applied only on a per call basis, it preserves
valuable DSP resources that may be required for other functionalities. An advantage
of using the Opus coder is that it consumes less bandwidth than G.711 and
overcomes packet loss (by dynamic packet redundancy), allowing the SBC to support
more concurrent calls than with G.711 for the same bandwidth. This mode is useful for
WAN networks that are relatively stable, allowing the use of G.711 whenever possible
and switching to Opus only during adverse network conditions.
