Get rid of Auto Accept.
If you don’t want nuisance calls, don’t put in a blanket slip. Tell it the hours you don’t want calls.
Or DND.
But putting in slips, and then complaining about getting calls for trips? Get out of here.
Unreal.
It is more important for trips to be covered than it is for you to be bothered. Turn your phone off.
This is the answer.
