[VoiceOps] False 911 calls and old abandoned DID

I've definitely had this happen to me.  I lived in a house with old copper
that was poorly installed, but no actual service on it.  Because I didn't
need it, I never gave it any attention...until the second time cops showed
up at the door thinking someone was being killed.

To be clear, this phone number is NOT with us, never ported, no connection
that I can find to this customer other than the CNAM is theirs.  I have
zero control of it.
