I am totally unsurprised by this situation:
Robocallers and spam callers are getting quite good at masking their identify. They do this partly by “spoofing” local numbers, making it seem like a legitimate local number is calling to increase the likelihood that you’ll answer. That’s the reason, according to Hiya, that around 9 percent of spam calls a month actually get answered by phone owners even though they don’t recognize the number calling.
Nine percent might not sound like much, until you consider the fact that 26.3 billion robocalls were made to American phones in 2018.
The nearly 50 percent of phone calls that go unanswered jumps way up to 76 percent of calls left unanswered — a little more than three out of every four — when the call comes from an unidentified or unfamiliar number.
In my case, that would be 100 percent. I never answer a call if the caller is unidentified (i.e. isn’t among my saved contacts). As a result, I always tell people to email their phone numbers to me first so I can add them to my contact list. Otherwise, their calls will be met with indifference.
Sucks, but that’s what happens when people use technology indiscriminately and unprompted.
