Answered question
Does Fizz/Videotron offer a service to block calls from anonymous "no caller ID" callers? I know some carriers do. When an anonymous caller dials your number, they get a message saying "this number does not receive calls from private numbers" or something to that effect. Anyone know how to set this up? Thanks! :)
I have not seen that feature with Fizz.
I tough I could set up my iPhone for it, but there is only the "do not disturb" and "block number" functions available.
Could be different on Android though.

@René D. looks like the same on android
Some Android phones, particularly samsungs allow blocking of Unknown or private numbers. iPhone, however doesn't offer that option, and there is no real way to block private/anonymous calls on iPhone, unless you use do not disturb 24/7 and use favorites for the people you know that'd call you.
Well, there are some third party apps that will manage it for you. I used to have one but I can't remember the name.
I dont think you can maybe in the future
Amir is right, 3rd party all can do it. Just replace the default phone app.
