You are still talking about hardware codec not WBS which is a HFP
feature, without a proper HFP implementation it is not even possible
to select AuriStream so it beats me why you want to bring that up.

Once you written and qualified your own HFP implementation we can
start talking about integrating it for desktop / laptop use, otherwise
the _only_ real option here is oFono, whether that requires a modem or
not is a different history, something that perhaps we should take on
to oFono to enable VoIP application to act as modems but that needs to
be discussed with oFono community.
