*77 to block anonymous calls doesn't work (traditional landline)

​Hi, I have the AT&T copper wire traditional landline service. The website for that service says to block anonymous callers, dial *77. When I dial *77 I just hear an error tone, a bit like a busy tone.​

​How can I block anonymous callers?​

These are the instructions I'm following: https://www.att.com/support/article/local-long-distance/KM1010649

Could be it's already set to on, try turning it off.

Unfortunately I have checked that. Dialling *87 to turn it off also results in a busy tone. 

Dialling *77 to turn it on results in a busy tone and anonymous calls still come through.

Report it. Not all features are available in all areas, could be that's the issue. Won't know if you don't report it. Anonymous call rejection doesn't do all that much.
