Calls coming in and no messages left. As I type this a call came in from 414-326-9237 and states on caller ID as Childrens Cance (Childrens Cancer) also has come up before as caller name 4143269237. So far I got calls from 414-326-9237, 414-369-6368 both as Childrens Cancer. They don't leave a message when the machine kicks on. I Won't answer if I don't know the number.
