Multicasting VoIP Stream
Posted on 2008-06-17
The agency I work for multicasts (stream) our board meetings to our employess over our VoIP system by sending a analog voice stream from the AV system into our gateway and then create a muliticast stream that is picked up by our VoIP phones.
This system works fairly well but seems to have some problems with certain ranges. In order to address this issue I put together a windows media server to multicast the meetings to employees desktops via windows media player. This works very well but unfortunately some employees want to continue to receive the stream over their phones and I've been asked to make this happen. Unfortunately I have not been able to get it working and I believe I have identified the issue as being a codec mismatch.
I'm using G.711 in my VoIP system but the media server seems to be unable to encode to this standard. I tried downloading the G.711 codec from Microsoft but I can not seem to get the server to use the codec. Considering that this codec is really only used for VoIP I'm wondering if it is supported.
1) Can windows media encoder generate a G.711 stream?
2) If not is there a third party application that could generate this stream and enable me to multicast this from the media server I configured?
Thanks for the help,
