To dissable GSM in the above SDP the only modification would be:
m=audio 12342 RTP/AVP 18 0 8 101
That will work, but the proper thing to do would be to also remove the 'a=rtpmap:3 GSM/8000' line.
Sure, but It would be more complex :) and as far as I expect it shouldn't be required (never tested anyway).
