Hi Marcel,
I don't see why not. Both Codec Negotiation and Wide-band speech are labeled optional
for HF/AG in Table 3.1. The only note there says: "If Wide Band Speech is
supported, Codec Negotiation shall also be supported." However, there is no note
vice-versa. So my interpretation is that Codec Negotiation can always be supported. Can
we check the test spec?
The problem I see is that by the time we register the SDP record, we still do
not know for sure whether the audio framework truly supports mSBC.
so we want to expose HFP 1.6 and codec negogiation all the time. Even if mSBC
codec is not available, because PA does not support it or is not running. I
read the spec the same way that this fully spec compliant.
If at some point in the future this changes, we can deal with that at that
point. No need to over engineer it at this point.
Exactly, Codec negotiation should always be supported.
. What my last comment was about is that:
If mSBC is not supported by PA, then it would be nice to not set the
wide-band speech bit in the SDP record to true. However, we do not know
this information in the current set up until too late.
Regards,
-Denis
