[Freeswitch-users] Is it possible to play a wav file to all legs at the same time?

Hello, I would like to play an announcement before call recording starts. I tried uuid_broadcast, but it plays the file on a-leg first and then after that it plays the file on the b-leg. It does not play the file on both legs at the same time. Is there a way to play a file on all legs simultaneously? Thanks, Ali Pey
