Cingular does have 611 and it in fact tells you to call that number as its telling you that calls to whatever number you're dialing are not allowed. Then I get the same message when I call 611. I called them this morning but since its under my husband's govt job and I don't know who the billing comes under, they would not discuss the matter. That's fine by me and I'm glad they do it for security reasons since my purse with all credit cards, ID, $500 pocket PC and everything else was recently stolen and they ran up all my credit cards. So I have to wait til he goes to work tomorrow. It makes a lot of sense what you suggested and I'm sure that must be it since none of the phone's settings are wrong.
I'll give an update when its resolved so that people with this problem in the future might know how to get it fixed.
Thanks for your help.
