TRI-STATE (WFIE) - Oakland City resident Dennis Smith says he's been getting plenty of those unwanted calls.
Smith says he never called Jackie's phone.
Experts say not all "spoofing" is done off shores.
There are heaps of apps anyone can use to spoof calls one at a time.
Since we started this conversation, lots of you have told us about being spoofed.
Calls will sometimes say someone you love is in trouble, or hurt, or in need of money.
People believe it because their caller-ID was so convincing.
Others said they've had death threats from people on the receiving end of relentless phone calls from your number, calls you never placed.
It's such a problem, Vanderburgh Sheriff's Office and other law enforcement agencies are now using social media to educate people about it, in an effort to protect people who may not realize what's happening until it's too late.
A good rule of thumb is before you act, hang up.
