General How to block calls?

view story

http://androidforums.com – Hey everyone, Does anyone know how to block calls or send certain callers directly to voicemail on this phone? Everywhere I looked says ice cream sandwich can do it and to just go to the settings of the contact card and the option should be there but I don't see it. On my last device which was running Froyo the option was there. All I've been able to find is Call Restrictions on the Call setting but the only options are to either block all or only allow contacts. I want to be able to restrict certain numbers but not all the time and not so generalized. Help? (General)
