CDR select seperate inbound or outbound traffic

Hi Freepbx,

Is there an easy way to just show inbound calls or just outbound calls. Or see if a call record is outbound or inbound.
I can not get managed to see the differences between inbound or outbound routes. I can recognize the source and destination, but that is not always inbound and outbound.

I hope I explained myself a little bit understandable?

Hope to hear any tips.
Thanx in advance!
