Does the spam blocker only work when nomorobo is activated?
It's two different features. You can enable one, disable the other, vice versa or none.
How do I enable or change the spam blocker settings without activating the nomorobo?
I think the only choice is to either opt-in or out of Spam Blocker. I'll have to log in my account to verify.
Log in your Cox account > navigate to Voice Tools > expand Settings > Spam Blocker > Customize. Not much in there but it's how you do it.
It's working now I had to select the settings I wanted and refresh the page a few times for some reason.
