I'm using mediastreamer2 to receive / send RTP data.
I would like to use the filter MSConf for multiple audio stream. By following instruction, a simple communication between a phone and PC is working. Now I've created a conference but when I don't have any more sound. I've done something like this :

ms_filter_link (stream->rtprecv, 0, stream->decoder, 0);
ms_filter_link (stream->decoder, 0, stream->dtmfgen, 0);
ms_filter_link (stream->dtmfgen, 0, room, 0);
ms_filter_link (room, 0, stream->soundwrite, 0);

ms_ticker_attach (m_ticker, pRtp->m_rtprecv);


MSFilter * room = ms_filter_new (MS_CONF_ID);

With this I can't hear any sound. If I don't use room and directly go to soundwrite, it's okay.
Could you help me ? I can't find any example with audio conferencing.

msconf is little bit tricky... there are some rules about the links. The best way to learn how use msconf is read the code.
input 0 is the local source (soundcard)
input (i*2+1) is the source of remote i-th call (rtp decoded data)
output 0 is the local output (soundcard)
output (i*2+1) is the output for remote i-th call (data to encoding and send to remote point)

the (i*2) input and output can be used for pumping/send audio from/to other sources/destinations
