Hi Jade,
You need to say what profile "101" is.
So, you need to include a line like this:
a=rtpmap:101 telephone-event/8000
"telephone-event" tells the remote side
that you can receive RFC2833.
So, your SDP will look like this:
v=0
o=jade 2890844526 2890842807 IN IP4 11.11.2.2
s=POI Seminar
i=A Seminar on how to make Presentations on the Internet
u=http://www.ee.org
c=IN IP4 11.11.2.2/127
m=audio 49170 RTP/AVP 0 101
a=rtpmap:0 PCMU/8000
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-15
