Freepbx doesnt log any incoming call

I have problem witch my freepbx. From 2 maybe 3 months i have nothink about incoming or outgoing call in /var/log/freepbx
I use redirect to my cellphone if i am out off office, and then my cellphone recognize incoming call as call from my number - not from caller number. Before issue i have been able to check this caller numer in logs. Now i cant and i cant call back to my caller, What can be purpose of this? where i can turn on this?
