[Freeswitch-users] playing a message while bridging

Hi is it possible to play a message while bridge is taking place, like <action application="set" data="ringback=/message.wav"/> <action application="bridge" data="sofia/internal/211%192.168.11.30"/> I've tried many combinations but sometimes I get server failure and in the best case the message file is played like beep beep . .. (but it's a voice message)!!! and it never works for now I'm using answer and playback and then I bridge but I wanted to see if it is possible not to answer the call thanx
