Galaxy Nexus - How do I start adding strangers' numbers to "auto-reject"? I regularly get phone calls from people trying to reach an old folks' home and I want to outright reject those automatically (without any "send to voicemail" ideally).

This was fairly painless on the Galaxy S: from the Call Log, tap-hold on the bad number, menu pops up, select "add to auto-reject". [Auto reject was enabled in the phone's settings before]

How do I achieve the same thing with the Galaxy Nexus?  I'm figuring the same feature should be available from the stock ICS somewhere.  If not, I'm open to lists of auto-reject apps.
If it's the same people ringing you regularly what you could do is:


Add them as a contact, under 'Ignore1', 'Ignore2' etc. whenever they
ring 
Go to Contacts -> Select 'Ignore1' -> Options (or action menu) -> Select 'All calls to voicemail'


Or if you don't like this method then you could try:
