Caller ID

I am a secret ninja.  Ok.  That was a lie.  I just like to think that in my head when I can see who is calling  on my work caller id.  So imagine my disappointment when one of those "out of area" or "Salem" people call.  That means I have to use my brain and try to associate a phone number (if there is one) with a client.  That takes a lot of brain power.  So what really amuses me is those people who call, but won't leave a voice message if no one picks up.  Instead, they will call every five minutes until someone answers.  And what happens when I answer?  I put you through to the bosses voicemail.  I don't see how my involvement in the process was necessary but ok.
