Is there any way to set someone to a silent ringtone? I see there is a way in contacts to cause a contact to go straight to voicemail, but I don't want the contact to know that I set it that way. I assume when I enable the "straight to voicemail" setting, the person on the other end will know something is different. I just want it to seem normal for them. I want it to seem to ring for them, and then go to voicemail, but I don't want to hear (or see) anything on my end.
