Block voice mail

[valid]

I use GB rooted and I have a phone number in my blacklist. Works great. But I still receive a voice mail from that number. Can that also be blocked?

check your phone blocker options. it might have the option to answer/hang up quickly.
of course, if you're on a limited plan it could cost you minutes.
I use root call blocker and it has several blocking methods
