Answered call and heard a brief phone dial before a recorded voice said "This is Linda Adams.  How are you today?"  Hung up and phone # is now blocked.

Received this call unsolicited on my cell phone which I didn't recognize so I didn't pick up.  No voice mail was left but it says Denver, CO.  I don't even KNOW anybody in Colorado so it's now blocked on my phone.  I have NO idea what this may be but I DON'T WANT IT!!!!
