Hi Thomas, I was reading old messages on freeswitch-users mailing list and I found one your old request. As I am facing similar issue and I would like to know if you already found a way to handle SIP INVITE to endpoints in order to join the audio stream on IP multicast. I am going to investigate on sofia sip internals in order to understand how to generate SDP that specifies audio stream on IP multicast. Many thanks in adavance.

Hi,
i want to stream audio (from file and live) from FreeSwitch to multiple SIP endpoints (these are proprietary). Because of bandwith limitations we have to use IP multicast for audio data.
Now the question: how can i do this smartly in FreeSwitch?
I have read some Wiki entries: - mod_esf: seams to use multicast, but i couldn't find usage information - mod_shout: streaming, but from internet ? MP3, but i want wav-files to stream - mod_local_stream: seams to play files in a loop, i want to play a whole file once. - mod_conference: seams not to support IP multicast
Im searching for a simple way to send a SIP INVITE to all my endpoints and then stream audio (live from soundcard or from file) over IP multicast to all these endpoints.
Thanks in advance, Thomas
