Surprise visitor

We had a surprise visitor last night. We're sitting there watching tv, waiting for Gilmore Girls to come on and waiting for Tom to get home. I hear someone loudly knocking on the door. I know it's not someone we know, because anyone we know well knows that there's a doorbell inside the door. So I approach cautiously, looking out the window before opening the door. It's a policeman!
"We had a 911 call from this address?" "Oh! The baby was playing with the phone!" So he said it was ok, but took my name, birthdate, and phone number and suggested I check the phone since it was busy when they called back. I apologized again. He was very very nice about it.
What are the odds that he would dial those particular numbers, in order, and when the phone was on!
