I don't see an action on your screenshot, but whatever you define there it will execute that in pre-call moment if the record matches your condition. So, yeah, 15 minutes ago last attempt? >> execute the action you've defined.
This page explains the conditions: https://help.mypurecloud.com/articles/add-rule/
Maybe worth noting: this will only work for outbound (dialer) calls related to a campaign where you assign this rule to.
Hope this helps.
