Why did my phone lose a call answering feature?

[Android Central Question]

My phone had the option to direct a call from a contact straight to voicemail. I created a contact for repeated spam numbers and directed them all to go straight to voicemail, but for some reason that option has disappeared.

I haven't changed any of the apps on my phone relating to call answering, and everything is up to date. What happened to my option?

Samsung Galaxy On5
Android version 6.0.1

Thank you.
