I would like to create a 3-user conference from a 2-user call (bridge) without calling the third user twice.<br><br>The scenario is the following:<br>1. user 1000 calls user 1001 (that responds);<br>2. user 1001 may decide to create a 3-user conference by transferring the execution to an extension that use conference_set_auto_outcall to invite user 1002 and create the conference.<br>
<br>&lt;action application=&quot;bind_meta_app&quot; data=&quot;3 b s execute_extension::cf XML features&quot;/&gt;<br><br>&lt;extension name=&quot;cf&quot;&gt;<br>    &lt;condition field=&quot;destination_number&quot; expression=&quot;^cf$&quot;&gt;<br>
        &lt;action application=&quot;answer&quot;/&gt;<br>        &lt;action application=&quot;transfer&quot; data=&quot;-both 3000 XML default&quot;/&gt;<br>    &lt;/condition&gt;<br>&lt;/extension&gt;<br><br>&lt;extension name=&quot;nb_conferences&quot;&gt;<br>
    &lt;condition field=&quot;destination_number&quot; expression=&quot;^(3000)$&quot;&gt;<br>        &lt;action application=&quot;answer&quot;/&gt;<br>        &lt;action application=&quot;set&quot; data=&quot;conference_auto_outcall_timeout=20&quot;/&gt;<br>
        &lt;action application=&quot;set&quot; data=&quot;conference_auto_outcall_flags=none&quot;/&gt;<br>        &lt;action application=&quot;set&quot; data=&quot;conference_auto_outcall_caller_id_name=${effective_caller_id_name}&quot;/&gt;<br>
        &lt;action application=&quot;set&quot; data=&quot;conference_auto_outcall_caller_id_number=${effective_caller_id_number}&quot;/&gt;<br>        &lt;action application=&quot;set&quot; data=&quot;conference_auto_outcall_profile=default&quot;/&gt;<br>
        &lt;action application=&quot;conference_set_auto_outcall&quot; data=&quot;user/1002@${domain}&quot;/&gt;<br>        &lt;action application=&quot;conference&quot; data=&quot;$1@default&quot;/&gt;<br>    &lt;/condition&gt;<br>
&lt;/extension&gt;<br><br>At this point user 1002 receive two simultaneous calls: one from user 1000 and one from user 1001 (I&#39;m using softphones).<br><br>The behavior I would like to achieve is that user 1002 only gets one call from user 1001 or from the conference.<br>
