It appears someone has hacked into my phone sys and is placing calls to this number almost every day from my phone. I am not at home, nobody is at my home.

Did you figure it out? That number is in my phone bill as well, shows up as outgoing 3 times a day. I've never called that number

It is a vm check dial number for home phone vm. Like how cell phones have a short cut number to get to their vm, there is still a full number attached, like this one

multiple calls a day with no messages left.  Is is actually Charter communications testing voice mail.

iI have multiple calls from this number including yesterday and i didn't even use my house phone cause its dead. The only thing is that it shows up as outgoing calls....
