Hi Scenario: - SIP only - inbound call, hits dialplan - call answered, some IVR used - call bridged to selected department The problem is, that I would like to play music on hold while trying to bridge. FS seems to completely ignore custom ringback settings: <action application="set" data="ringback=myfile.wav"/> <action application="set" data="transfer_ringback=myfile.wav"/> <action application="bridge" data="{ignore_early_media=true}sofia/internal/x@y" /> tried also with: <action application="bridge" data="{ignore_early_media=true,transfer_ringback=myfile.wav,ringback=myfile.wav)}sofia/internal/x@y" /> and <action application="set" data="ringback=myfile.wav"/> <action application="set" data="transfer_ringback=myfile.wav"/> <action application="ring_ready" /> <action application="bridge" data="{ignore_early_media=true}sofia/internal/x@y" /> All with no success. I see in console that variables are set, but for some reason FS ignores them and there is no audio while bridging. At the same time I can play/stream sound file before bridge, but this operation is blocking and stream can not be run in background so it can't be used for MoH purpose. Any hints what should I check or how to achive nonblocking MoH?
