[Freeswitch-users] stream a file multicast with mod_esf

Hi, i want to stream a file per IP multicast with mod_esf. I can stream IP multicast with: pa call stream XML and in XML dialplan: <extension name="stream"> <condition field="destination_number" expression="^stream$"> <action application="answer"/> <action application="esf_page_group" data="224.168.168.168 34567"/> <action application="esf_page_group" data=""/> </condition> </extension> and i can also play files with 'playback' app, BUT: how can put these 2 things together? May be its trivial, but i cant get it make working with 'originate' or 'uuid_broadcast' or 'bridge', 'transfer' and so on ... Thanks in advance, Thomas
