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