The UAC could know in this way that the UAS supports also those codecs (even if they would not be used in this SDP session negociation, maybe later in a new re-INVITE). About the "m" lines, a UAS cannot indicate more "m" lines than received in the offer since it's a SDP response (AFAIK). PD: Please, when writting a new mail don't take any other mail to write above. Use "Create new mail" button. If you press "Reply" over any other mail to create a new one, your mail will include a "In-Reply-To" header and will appear in a wrong thread in mail clients.
