Today while testing some default conference features ( thus using context "default" and all vanilla configs) 
<span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">i&#39;ve discovered that:</span><div><br></div><div><div> &lt;extension name=&quot;wb_conferences&quot;&gt;</div>
<div>      &lt;condition field=&quot;destination_number&quot; expression=&quot;^(31\d{2})$&quot;&gt;</div><div>        &lt;action application=&quot;answer&quot;/&gt;</div><div>        &lt;action application=&quot;conference&quot; data=&quot;$1-${domain_name}@wideband&quot;/&gt;</div>
<div>      &lt;/condition&gt;</div><div>    &lt;/extension&gt;</div></div><div><br></div><div>In the profile &quot;wideband&quot; at conference.conf.xml &lt;param name=&quot;moh-sound&quot; contains value=&quot;$${hold_music}&quot; but this global channel variable is defiened at vars.xml and is local_stream://moh/8000</div>
<div><br></div><div>&lt;X-PRE-PROCESS cmd=&quot;set&quot; data=&quot;hold_music=local_stream://moh/8000&quot;/&gt;</div><div><br></div><div>So when i entered into wideband or uwb or even cdquality (it doesn&#39;t matter because in each profile there is param-name &quot;moh-sound&quot; contains $${hold_music}) conference i&#39;am will be listening moh/8000.</div>
<div><br></div><div>To listen moh/16000, moh/32000, moh/48000 i should manually adjust corresponding music streaming quality, i.e for example for wb-conference</div><div>&lt;param name=&quot;moh-sound&quot; value=&quot;local_stream://moh/16000&quot;/&gt;</div>
<div><br></div><div>But there is another issue :) If do not install {hd,uhd,cd}-moh (assuming that moh/8000 i do install) therefore my $${sounds_dir} will be containing only 8000 stuff and when i will be enter one of hd/cd quality conferences i would get this error</div>
<div><br></div><div>mod_local_stream.c:393 Unknown source moh/32000, trying &#39;default&#39;</div><div><br></div><div>and thus listening default moh ($${sounds_dir}/music/8000).</div><div><br></div><div>What would be better: to get this error or manually additing each profile at conference.conf.xml for listen hold-music @ HD-quality, there is the question :)</div>
<div><br></div><div>I REPEAT I&#39;m talking about default configuratin (i.e. vanilla) not production cases :)</div><div><br></div><div><br></div>
