Hang up call to my voicemail.  Although it is a legit number belonging to Michael McDermott, the caller ID was probably SPOOFED.  Getting a lot of these lately.  In my outgoing message I tell people to leave a message or be blocked.  So I am blocking the number.  It is no coincidence that the number shares the same area code and prefix as mine.  Getting a lot of these calls lately to both my cell and voicemail line.
