[Freeswitch-users] announce conf count (total callers minus 1)?

this works great, thank you to whomever created it. is there a way to make the conf count = list count -1 so the playback will only speak total "other" callers instead of including the person who press the option? conf/dialplan/default/01_Announce_Conf_Count.xml: <include> <!-- Sample dialplan for announcing the call count --> <extension name="Announce Conf Count (Inline)"> <condition field="destination_number" expression="^ANNOUNCE_CONF_COUNT_PRIVATE$"> <action application="set" data="conf_count=${conference ${conference_name} list count}"/> <action application="log" data="INFO ${conf_count}"/> <action application="say" data="en number pronounced ${conf_count}"/> </condition> </extension> </include>
