Called me every day that my home alarm went off and someone was attempting to break in my house. They never got in my house but it was odd that for a whole week there were 4 attemps of someone trying to get in my house and this nubmer called every day and only on those days that my alarm went off. Messages on my machine were no one talking but there was like air blowing in the background or driving in a car. When i tried to call it back from the house it tellsme that due to network difficulties my call can not be completed at this time. When i call it from my cell phone it tells me that the subscriber i am trying to reach has traveled outside of the network.
Unfortunately, I never seem to be near the phone when this one calls. The CallerID just reads, "LOCAL CALL". There's never a message left - just a sound, like a truck engine running. And one time, it sounded like someone breathing (but, quietly - not in an obscene phone call kind of way).
