The majority of silent or abandoned calls are made and caused by automated calling systems known as dialers, or predictive dialers. If the dialer makes a call but there is no call centre agent on hand to deal with it, the person being called will hear silence on the other end of the line.
Correspondingly, why do people keep calling me and hanging up?
Originally Answered: Why do random number calls and hang up? These may be prank calls, but probably more likely cold callers who didn't expect a particular person to answer the call - or it could be someone validating that a phone number is real for later cold calling.
What to do if someone keeps calling you?
Hang up and report it to the Federal Trade Commission at complaints.donotcall.gov or 1-888-382-1222. If you're getting repeated calls from the same number, you might want to ask your service provider to block the number; for calls from different numbers, ask if they offer a service to block unwanted calls.
What is the purpose of silent calls?
When the other end of the line is silent, it could actually be an automated computer system that's calling for the purpose of building a list of humans to target for theft. These silent calls are testing phone numbers to see which ones have a human to pick up and talk to someone.
Can you get hacked by answering a phone call?
Answering a call will do absolutely nothing, apart from the usual things where you can hear the person on the other side. Unless you install an application that they ask, give it permissions and full access to your phone, there is no point where you will be hacked. It's very unlikely to be hacked that way .
