[Freeswitch-users] Stream audio file/live to multiple SIP endpoints with IP multicast

[Sluschny, Thomas]

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
