Looks okay to me. Perhaps you are not looking at the m=audio line in the
SDP which you will is different - this reflects the difference in the
offered codecs.

You might be expecting to see all of the codecs itemised in the a=fmtp
lines - this is known as verbose-sdp and is disabled by default.

Have a look at:
