CID has unknown name. I did not answer and they left no message. Just as some others have reported, I received a call yesterday from a different number 909-366-4126 unknown name and I didn't answer and they left no message. Very irritating! I get calls everyday from unknown numbers and I'm on DNC list.
I do not answer calls where caller is unknown - no message was left on my voice mail. Whitepages shows this to be Washington DC #. I assume a legitimate caller would leave a message.
