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?

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.
