BB Bold 9700 :: Calls Are Blocked And Asks To Enter 10 Digit Number?

Every time I try to call a number (LAN LINE) that has a block on unidentified callers, I get the message "The number you are calling does not accept unidentified calls please enter your 10 digit phone number" The funny thing is that this problem just started to happen. A week ago it was fine. When I do call a number that is not blocked, my number comes up correctly on the caller ID but shows as unidentified. Sometimes, it shows up as international.Now, funny thing is that if I put my SIM in my Pearl, I can make calls no problem. There are two settings on the Bold under general options. One is called "Restrict My Identity" In this case, I have have it set to NEVER. I have also tried NETWORK DETERMINED, but neither of them make difference. The other setting is called "Show My Number" and this is set to YES.I have talked to AT&T until I am blue in the face. They say it is a problem with the phone and that it needs to be replaced. I hardly believe that. I have a friend with the same phone and it has the same problem.I did see some threads on this before in other forums, but never did see an answer to the problem.Finding a solution would be very nice.Already tried doing a factory reset and a security wipe on the phone.
