Hi<br><br>I am trying to play different moh sound for each conference call by passing a variable to moh-sound from the dialplan to autoload_configs/conference.conf.xml<br><br>In my dialplan/default.xml<br><br>    &lt;extension name=&quot;conference_incoming&quot;&gt;<br>
        &lt;condition field=&quot;destination_number&quot; expression=&quot;^(.*)$&quot;&gt;<br>                &lt;action application=&quot;set&quot; data=&quot;knowlus_hold_music=$1&quot; /&gt;<br>                &lt;action application=&quot;conference&quot; data=&quot;3001@default&quot;/&gt;<br>
                &lt;action application=&quot;hangup&quot; /&gt;<br>        &lt;/condition&gt;<br>    &lt;/extension&gt;<br><br>In my autoload_configs/conference.conf.xml<br><br>&lt;param name=&quot;moh-sound&quot; value=&quot;local_stream://${knowlus_hold_music}&quot;/&gt;<br>
<br>However, it does not work. It is not able to expand the variable ${knowlus_hold_music}<br><br>In the log<br>2012-02-15 19:55:31.195264 [WARNING] mod_local_stream.c:393 Unknown source ${knowlus_hold_music}, trying &#39;default&#39;<br>
<br>Is it even possible to pass a channel variable to a config file ? Or is there another way to achieve what I am trying to do ?<br><br>Thanks. <br><br clear="all">regards,<br>Anita<br><br>
