Don't be angry, but I really don't know what "call" is per se.

I *think* it is when there are issues you get "called" to solve them. Like my pediatrician's office. If we ever have an emergency question, we can call anytime and talk to one of the pediatrician's in the office. They will either tell us to wait until morning and what to do until then, or send us to the ER. We had to use this once when DD had a massive allergic reaction to penicillian and was only 6 months old.

Is call similar to that for you? Or something else?

I am not meaning to be offensive, just as a corporate America desk jockey, this is something I hear but don't think I understand.
