Спасибо за помощь, решил все путем через extensions_override_freepbx.conf :
exten =>recordcheck,n,MixMonitor(${MIXMON_DIR}${YEAR}/${MONTH}/${DAY}/${CALLFILENAME}.${MON_FMT},abi(LOCAL_MIXMON_ID)${MIXMON_BEEP},${MIXMON_POST})
Заменил abi на ai (просто удалил символ b)
Результатом буыл:
exten => recordcheck,n,MixMonitor(${MIXMON_DIR}${YEAR}/${MONTH}/${DAY}/${CALLFILENAME}.${MON_FMT},ai(LOCAL_MIXMON_ID)${MIXMON_BEEP},${MIXMON_POST})
2.)
var\www\html\admin\modules\callrecording\functions.inc.php
Find string
$ext->add($context, $exten, ‘’, new ext_mixmonitor(’${MIXMON_DIR}${YEAR}/${MONTH}/${DAY}/${CALLFILENAME}.${MON_FMT}’,‘abi(LOCAL_MIXMON_ID)${MIXMON_BEEP}’,’${MIXMON_POST}’));

И все замечательно работает.
