Hi. I need to set a conference parameter - "caller_id_name". So in my dialplan I do next:  <action application="set" data="api_result=${conference($1 set caller_id_name ${Orig_Ptt_Ext})}"/>  <action application="set" data="api_result=${conference($1 set  caller_id_number ${Orig_Ptt_Ext_UUID})}"/>  <action application="answer"/>  <action application="conference" data="$1@simple++flags{nomoh}"/> . But it is not right, because the conference possibly does not exist at that time (will be created at " conference "). Then I tried to do next:  <action application="answer"/>  <action application="conference" data="$1@simple++flags{nomoh}"/>  <action application="set" data="api_result=${conference($1 set caller_id_name ${Orig_Ptt_Ext})}"/>  <action application="set" data="api_result=${conference($1 set  caller_id_number ${Orig_Ptt_Ext_UUID})}"/> But it is also not right, bacause dialplan stops at doing "conference". So, what am I suppose to do to make it right? May be there is some way to pre-create conference (without real members)? May be there is a way to configure some actions to be done after creation of conference - something like "execute_on_conference_create"? With best regards, Shumaev D.A., programmer @ KBR Ltd.
