I was just commenting on a post that claimed there is no way to know if anyone called while underground, without receiving a voice mail.
I provided my experience (I'm sorry if I wasn't clear enough about the fact that I am providing my own case, but it seemed obvious) on this issue which contradicted the aforementioned claim.
All I was saying is that not all users are affected (like myself). I was in no way trying to downplay your issue, neither was I advocating its presence.
