Missed Connection

So there's a pay phone at my job that rings once every morning at 5:20. Every. Morning.
And I'm sure there's a simple explanation, but.... I can't help but wonder if there's a spy waiting for a signal or a time traveler waiting for a way back home. I want there to be a real story attached to this. I want there to be some mystery in my life. I want to know Harry and Hermionie are waiting for the all clear. I want to know that our nation is safe once again. But I can't, because NO ONE EVER ANSWERS IT!!!! No one is ever in the store or next to the phone when this happens. There has never been a person who hangs out by the phone and then strolls out with hood up all nonchalant like, and I really want there to be. I want someone to pick up the phone and be sucked down the wire. I want someone I notice to disappear as soon as it happens. Seeing as how it keeps ringing, I'm of the opinion that whatever is supposed to happen, hasn't happened yet.
So if there is anyone who can tell me a better way to catch this spy/wizard/time traveler please tell me because I am not as imaginative as I pretend.
