If we follow the logic in this document, I would suggest that G.722 MUST be
implemented in all cases. For all practical purposes G.722 is always
available. It might not be provided by the platform, but the complexity of
implementing it is extremely low, and there is no IPR cost. G.722 is
already part of the current WebRTC code base in both Chromium and Firefox,
but it is disabled during compilation from being included in the web
browser build. Adding support for G.722 in two current major
implementations would require one change in defines.
