I would like to suggest make MONITOR_FILENAME indefinitely inheritable in [ext-queues] so that custom code to call an agent has access to the call recording filename for integration with other systems.
I believe that all is require is to change
$ext->add('ext-queues', $exten, '', new ext_setvar('MONITOR_FILENAME','/var/spool/asterisk/monitor/q${EXTEN}-${STRFTIME(${EPOCH},,%Y%m%d-%H%M%S)}-${UNIQUEID}'));
to
$ext->add('ext-queues', $exten, '', new ext_setvar('__MONITOR_FILENAME','/var/spool/asterisk/monitor/q${EXTEN}-${STRFTIME(${EPOCH},,%Y%m%d-%H%M%S)}-${UNIQUEID}'));
in admin/modules/queues/functions.inc.php
