Does anyone know what this movie is?

I honestly cannot remember what the name of this movie is (obviously),
and would like if someone could help! (: Either way, from what I can
remember about the movie!

It was a movie where the main character gets a cell phone call. These
people are apparent strangers (or they could know each other, I can't
remember), but the main character has to get to the person who he
called before the person is killed.

It came out a few years ago, and it's NOT 88 Minutes. I know for a
fact, because it's a different idea. Any help to figure out what the
movie is - would be helpful!
Alright, I definitely know it's not "When a Stranger Calls" or "Eagle
Eye". My sister has seen One Missed Call - and she says it doesn't
sound like it. So, perhaps something that is more along the lines of
what 88 minutes is. Because she said it sounded a lot like it. (But I
know the movie I'm thinking of didn't have Al Pacino.)
