This phone number has called me several times today. I say hello and nothing but dead air and then a disconnect. Every time I call this number I get a busy tone. I called Embarq and they said it's a cell phone.
I have Sprint for my cellphone. I sent a text to my mom's landline to see what would happen. This was the number that showed up on the caller id. It played my text back to her (as speech) and allowed for a few basic replies to be sent back.
