You should call your telephone company and report these types of incidences otherwise you can never get them stopped. I think they are people fishing to see if you are home or not and for any information about the person living or working at the number.
This number appears on my caller id and I have no idea who this is. They never leave a message and I see other people have the same issue with the number. Is it possibly someone trying to see if we are home or trying to find information from us. The call was made from this Macon number.
