[Freeswitch-users] How to connect SIP call to rtsp stream

Good day, I'm trying connect incoming video call into rtsp stream (e.g. security camera h.264 video only or h.264 video + PCMU audio). I tried these two approaches: <action application="playback" data="av://rtsp://192.168.2.7/streaming/channels/103"/> or <action application="playback" data="rtsp://192.168.2.7/streaming/channels/103"/> And FS doesn't like it: [ERR] switch_core_file.c:306 Invalid file format [av] for [rtsp://192.168.2.7/streaming/channels/103]! or [ERR] switch_core_file.c:306 Invalid file format [rtsp] for [192.168.2.7/streaming/channels/103]! What is the right syntax to accomplish this? Also, which modules need to be compiled & loaded for this to work? Many thanks, -victor
