As far as I know this can only be accomplished with an app that listens to events. In mod_conference you will see that there are start talk and stop talk events. If you monitor all conference members then you could pause/un-pause based on whether anyone was speaking.<br>
<br>I recommend you read up on <a href="http://wiki.freeswitch.org/wiki/Event_Socket_Library">ESL</a> and <a href="http://wiki.freeswitch.org/wiki/Mod_conference">mod_conference</a> on the wiki as a starting point.<br><br>

<div><font>How to pause and resume play an audio file in conference?
For example: I create a conference room with some members, and play an
audio file to them. When someone start-talking, I pause the playing. When nobody
talking, I resume play the audio file.</font></div></div>
