A method, performed by a user device, may include detecting an incoming call; determining whether the incoming call is associated with a very important person contact; directing the incoming call to a voicemail system, when the incoming call is not associated with a very important person contact; and providing, when the incoming call is associated with the very important person contact, an instant response message to a device associated with the incoming call without answering the incoming call. The method may further include providing reminder, including a ranked callback list of missed calls, to the user at particular intervals.
