How to block a number on iPhone?

I have the need to block several numbers from repeatedly calling my phone. Any
suggestions on how to do this is greatly appreciated.

iPhone number
One trick is to download a "silent" ringtone to your phone, and assign it to those numbers

...and that is precisely why I had asked about the silent ringer. It sure does give me a sense of satisfaction when I see that it works...kinda petty...but hey! LOL

You can go to AT&T and set up a block of telephone numbers. There is a charge for this service.

its a function of AT&t not the iPhone... you can as I do, save the number as a contact with a name of "DO NOT ANSWER"

LOL funny thing also, if you want to make the call not so annoying even when you have " do not answer"

Make their ringtone your favorite song. Double the satisfaction, you dont answer them, and you get to hear your favorite song hahaha

I beg to differ... Not being able to block a number is a function of iPhone! I've had AT&T service for some 18 years now, and every smartphone I've had previous to the iPhone has allowed me to block a number from the phone itself. Nokia, motorola, palm etc. I was in utter shock when I moved to the iPhone and found I could not. Check the archives for my messages in July of 2009 for my shock and amazement.

I too just set the offenders up to be a "Do Not Answer" contact, with a "no ringtone" ringtone. I don't want to pay AT&T 4.99 extra a month for them to block the number, none of their other phones require it. That is just a way for AT&T to futher separate iPhone users from their money.
