Thanks,

I have received calls on my cell phone for months.  I finally came up with a solution that routs them to a no ring box.
After the first call I add them to my contacts like this.  
1. I add the number for the name, Z 623 255 7164 (This puts them at the end of my contacts list)
2.  then I set the ring tone to none.  Since the call will be marked as missed it goes to the missed calls box
3. I set the missed calls box ring tone to none.

Now when they call back it just dies and I don't know about it till I look at my the next time. I just clear the calls and live life without them annoying me.
