For everyone: if you don't recognize the number--or if it comes in as "unknown" or similar--ignore it! Let it roll to voice mail. If it is a real, legit caller, they'll start to leave a message, the you decide if it is a legit caller.
If everyone will just not answer any of these spam callers, they won't have anyone to harass.
BTW--the prefix "116" (as in 214-116-5485) is not a legit prefix in 214 or anywhere else in the USA.
