This is because, most likely, the number displayed is SPOOFED, meaning its a FAKE NUMBER (and name) generated by a computer to HIDE the real number. This is a favorite tactic of SCAMMERS and SPAMMERS.

It's a cruise scam "survey. They left me a voice message with a few numbers to punch, including an opt out. Say what? I'm gonna punch some numbers from an unknow source? DUH!!!

Punching "unknown" numbers on your cell phone is not like on a computer. You're not gonna get a virus on your phone.

He won't get a virus on his phone by punching numbers in, but the crooks will get a confirmation that his phone is live for robocalls from filthy boiler rooms in South Asia, South East Asia, Belize, etc.
