+  Opus is the default audio codec in WebRTC. WebRTC is available in
+  Asterisk via SIP over WebSockets (WSS). Nevertheless, Opus can be used
+  for other transports (UDP, TCP, TLS) as well. Opus supersedes previous
+  codecs like CELT and SiLK. Furthermore, in favor of Opus, other
+  open-source audio codecs are no longer developed, like Speex, iSAC,
+  iLBC, and Siren. If you use your Asterisk as a back-to-back user agent
+  (B2BUA) and you transcode between various audio codecs, one should
+  enable Opus for future compatibility.
+
+  Opus is not only supported for pass-through but can be transcoded as
+  well.
