You can solve this issue by avoiding loopback. Don&#39;t use loopback unless there is absolutely no other alternative. Try replacing the loopback calls in the group definition to &quot;user/xxx&quot; instead:<br><br>   &lt;extension name=&quot;group_dial_sales&quot;&gt;<br>

      &lt;condition field=&quot;destination_number&quot; expression=&quot;^2000$&quot;&gt;<br>
        &lt;action application=&quot;bridge&quot;<br>
data=&quot;[execute_on_answer=&#39;limit hash callwaiting 
1000 1&#39;]user/1000, [execute_on_answer=&#39;limit hash callwaiting<br>

1001 1&#39;]user/1001&quot;/&gt;<br>     &lt;/condition&gt;<br>   &lt;/extension&gt;<br><div> </div>This is just off the top of my head, so please do the usual testing and tinkering before you report back that it does not work. :)<br>

Hello,<br>
<br>
I&#39;m trying to limit calls to one user with limit application, all<br>
works fine when a user dials to the number user (the caller is<br>
transfered to limit_exceeded extension)<br>
<br>
But when a caller dials to the 2000 extensions (a &quot;ring group&quot; to<br>
loopback channels) and one of the users (for example 1001) answer the<br>
call, the limit app removes the limit count for this channel when the<br>
loopback channel disappears (when the direct bridge occurs between the<br>
caller channel and callee channel).<br>
<br>
Where is the problem? How can I avoid that the limit app removes the<br>
limit for this loopback channel?<br>
<br>
There is the fragmet of my dialplan (is the vainilla dialplan from git<br>
with the limit action added)<br>
&lt;context name=&quot;default&quot;&gt;<br>
...<br>
 &lt;extension name=&quot;Local_Extension&quot;&gt;<br>
      &lt;condition field=&quot;destination_number&quot; expression=&quot;^(10[01][0-9])$&quot;&gt;<br>
        &lt;action application=&quot;export&quot; data=&quot;dialed_extension=$1&quot;/&gt;<br>
        &lt;action application=&quot;set&quot; data=&quot;ringback=${us-ring}&quot;/&gt;<br>
        &lt;action application=&quot;set&quot; data=&quot;transfer_ringback=$${hold_music}&quot;/&gt;<br>
        &lt;action application=&quot;set&quot; data=&quot;call_timeout=30&quot;/&gt;<br>
        &lt;action application=&quot;set&quot; data=&quot;hangup_after_bridge=true&quot;/&gt;<br>
        &lt;action application=&quot;set&quot; data=&quot;continue_on_fail=true&quot;/&gt;<br>
       &lt;action application=&quot;limit&quot; data=&quot;hash callwaiting<br>
${dialed_extension} 1&quot;/&gt;<br>
        &lt;action application=&quot;bridge&quot;<br>
data=&quot;user/${dialed_extension}@${domain_name}&quot;/&gt;<br>
        &lt;action application=&quot;answer&quot;/&gt;<br>
        &lt;action application=&quot;sleep&quot; data=&quot;1000&quot;/&gt;<br>
        &lt;action application=&quot;bridge&quot;<br>
data=&quot;loopback/app=voicemail:default ${domain_name}<br>
${dialed_extension}&quot;/&gt;<br>
      &lt;/condition&gt;<br>
    &lt;/extension&gt;<br>
<br>
    &lt;extension name=&quot;group_dial_sales&quot;&gt;<br>
      &lt;condition field=&quot;destination_number&quot; expression=&quot;^2000$&quot;&gt;<br>
        &lt;action application=&quot;bridge&quot;<br>
data=&quot;loopback/1000/default,loopback/1001/default&quot;/&gt;<br>
