I know in a lot of High Schools, they just confiscate.
I know college/university are used interchangeably in the U.S., but yeah, as far as I gather, a university professor can kick you out of their class for basically whatever they like. Of course, you are allowed to report them to their head or the Dean if they're acting tyrannical, but you shouldn't have had your phone out. You should have known that there was a zero tolerance policy for having your phone out in class, and it sure as shit should have been muted before you went in there.
I know tons of classes where it will be confiscated till the end of class, and plenty of professors that will do it. I know the dirty glares that happen when people's phones go off during lectures or during rehearsals. To be honest, I love your teacher for having a zero tolerance policy and treating people to it. If your girlfriend called, or your parents called, and you felt that it was that important that you needed to answer it and leave at that moment and take an absence, then that's your call.
If it was in the course outline, this is on you. You could have adjusted your behavior, changed classes, or just learned to deal with it. But no, your teacher was not in the wrong, and at most universities was very allowed to do what she did.
