Frank, Codecs are configured in the preference order of their use in SIP.
In your case, originating side offers a,b,c codecs and answering party supports b,c. So the negotiation is either on 'b' or 'c', as the codec 'b' has the higher preference on both the side thus media will flow on codec 'b'. Hope this helps.
