What is the "Smart" icon in my Galaxy S7 call log?

[Android Central Question]

I have a Galaxy S7. Occasionally there will be a call, sent or received, that has an icon with image of a phone receiver and the test Smart. I see it on a call to my voicemail, a phone number I called, and some missed calls that are likely spammers. Maybe not a big deal, just curious what it means. Google is fruitless since all my keywords are so common.

"The Smart Call function lets you know who's calling even when the number isn't on your contact list. When it's spam, you can easily block the call, and then take action by reporting it."
