ZOHO CRM Integration

Hello.
I’m using the Zoho CRM Integration with Vital 4.
I’m able to authorize the API Calls and SYNC the Contacts. But when i make a outbound call from my vital i’m not getting any record on the Zoho side.
Looks that vital is trying to run a “system” call with the CALL details… something like this:

Executing [log-call@crm-integration:10] System("PJSIP/1002-00000012", "/usr/share/vitalpbx/scripts/crm "logCall" "892d396700379457" "8689840000XXXXXXXX" "9X84282XXX" "1002" "9X84282XXX" "3" "ANSWERED" "10" "" &") in new stack

Nothing happens in the Zoho side…
but if i try to run the same system call in the console i get an error :

/usr/share/vitalpbx/scripts/crm "logCall" "892d396700379457" "8689840000XXXXXXXX" "9X84282XXX" "1002" "9X84282XXX" "3" "ANSWERED" "10" ""

What could be happening?
Thanks!
