Calls from one of my contacts (it is Verizon line) go straight to voice mail instead of ringing through. I verified my contact list to make sure this contact did not expect this to happen: the box to check for "send straight to voice mail" was not checked. Problem started a pair of days ago. My Galaxy S 2 is set to ring & vibrate. I tried to call to other cell phones from the same contact but no such problem exists. No problem also exists for other numbers of Verizon. When I try to call voice mail from my Galaxy it goes to that Verizon phone above mentioned. Will appreciate any help.
