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. Lorentz
