You can't do that on official, non-jailbroken phones; Apple doesn't allow third-party developers to integrate with the phone app.
You have a few options though. One is contacting your carrier as some companies offer this service. Another is to sign up for a service such as Google Voice or Line2 since they give you a number and allow you to set up rules for specific groups of callers. You may even be able to port your number to one of these services, though depending on your phone company it may not be possible to both port your number, and keep your plan active with a new number. You could always try the Youmail service, which is available in the app store and replaces your carrier's voicemail service. There are instructions for forwarding unanswered calls to Youmail, and you can block certain parties from leaving voicemail messages. But of course, they will still be able to ring through, and also they'll still be able to text you.
