Now I see where the confusion comes from.  Asterisk doesn't really speak 
English - or Chinese for that matter:-)  In telephony, there is no way for 
the callee to tell the caller to stop ringing - unless you "answer" it 
first.  Once you answer, you can do a number of things, the rudest being to 
immediately hang up. (I saw live people doing this intentionally.)  Your 
only other option really is to ignore.

I just thought up this simple method to ignore: divert the dial plan to 
simply Wait() an unreasonable amount of time in hope that the caller hangs 
up.

exten => s,1,Dial(yourcell,5)
exten => s,n,Wait(300)

That's assuming your provider provides disconnect supervision.  You can also 
Play(prerecorded,noanswer) if your provider supports it. (Won't hurt to try 
even if not - but disconnect supervision is a must.)
