Call divert settings on Android 6

Hi everyone, is it just me or where is the call divert (to voicemail) settings hiding on Android 6 (Marshmallow)? I know it used to be in the dialler app but the only thing I find there now is something called “X-Divert CFNRc Settings”. And what on earth is that? :wink:
Thanks if you have any ideas!

Ups. Found it. It’s hidden in plain sight under the settings for sim1 and sim2. My bad.
