title: Asterisk ConfBridge disable all sounds from conference (BabyMonitor)
body: <p>i am trying to get a Baby Monitor working with 2 phones on Asterisk (chan_pjsip) extensions.</p>
  
  <p>i tryed this config in /etc/asterisk/extensions.conf:</p>
  
  <pre><code>;Baby Monitor Conference
  exten =&gt; 222,1,NoOp(&gt;&gt;&gt;&gt; CONNECTING TO MONITOR MODE FROM REMOTE PHONE &lt;&lt;&lt;&lt;)
  exten =&gt; 222,n,Set(CONFBRIDGE(user,announce_join_leave)=no)
  exten =&gt; 222,n,Set(CONFBRIDGE(user,startmuted)=yes)
  exten =&gt; 222,n,ConfBridge(1)
  
  exten =&gt; 333,1,NoOp(&gt;&gt;&gt;&gt; CONNECTING TO MONITOR MODE FROM BABY'S ROOM &lt;&lt;&lt;&lt;)
  exten =&gt; 333,n,Set(CONFBRIDGE(user,announce_join_leave)=no)
  exten =&gt; 333,n,Set(CONFBRIDGE(announcement)=no)
  exten =&gt; 333,n,Set(CONFBRIDGE(user,quiet)=yes)
  exten =&gt; 333,n,ConfBridge(1)
  </code></pre>
  
  <p>But on extension 333 (Baby´s room) there are still join and leave notifications played.</p>
  
  <p>Any hints, what has to be done that sounds will be completely suppressed on extension 333?</p>
  
  <p>thx</p>
