This number called me just now. No message left. However, I dialed the number and got a recorded message, "this number is no longer in service." Funny, that I called this number two minutes after it called my number and it is seemingly "no longer in service."
The number was spoofed (i.e., faked). You can't trust that either the Caller-ID name OR the Caller-ID number will be that of the party that is calling you.
