Hi, List,
In rfc 2833 ,DTMF event use the same port as audio.
the SDP will 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 //101 is the payload type for DTMF
enent.
a=rtpmap:0 PCMU/8000
a=fmtp:101 0-15 // we only support 0-15 event.
Can the remote side read that the other side supports RFC 2833?
Best Regards,
Jade
