<p class="MsoNormal">Hi Josh,<br>
<br>
Use FS master, it has a new audio Jitter Buffer.<br>
<br>
Then you can use Opus with this setting in the codec config:<br>
<param name="use-jb-lookahead" value="1"/> . <br>
The other side must be sending FEC so you could profit from it.<br>
<br>
<br>
You can enable the Jitter Buffer in the dial plan:<br>
<action application="set" data="jitterbuffer_msec=2p:25p:"/><br>
And then enable PLC :<br>
<action application="set" data="rtp_jitter_buffer_plc=true"/><br>
<br>

Dragos<br>
