[Linphone-developers] Using MSConf - conference

[Raust Tamatea]

Hello,
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);

with

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.

Regards.
