Aastra XML scripts with 57i

I’ve Freepbx distro installed with the latest Aastra XML scripts.
My client keeps asking me if there is a way to display missed calls only instead of full call log. I’ve also noticed that there is some sort button when I go to “Callers” on the phone however pressing it doesn’t do anything. Does anyone have a clue what is it used for?
My old linksys phone could sort call log and show dialed, received and missed calls and i was really disappointed that Aastra 57i cannot do this.

Can someone help? Thanks.
