[Freeswitch-users] Dialplan appliction db?

Anyone point me to the wiki which describes the "db" application and its arguments? The following is a snippet from a dialplan. <anti-action application="set" data="continue_on_fail=true"/> <anti-action application="db" data="insert/call_return/${dialed_ext}/${caller_id_number}"/> <anti-action application="db" data="insert/last_dial_ext/${dialed_ext}/${uuid}"/> <anti-action application="bridge" data="user/1000@$${domain},1001@$${domain},1002@$${domain}"/> <anti-action application="answer"/> Thanks, Lars
