I received a call a short while ago from this number, and several calls from the same number over the last several weeks. The caller ID reads "MDSO", and I have no idea what that stands for or the reason for the calls. I make a point of not answering any numbers that I do not recognize, and this caller never leaves a message to help me identify who it is. Any information that you can offer will be greatly appreciated.
