Jens (JTR) Rasmussen posted a great explanation of the unexpected behavior for CWA and phone number normalization rules. Put simply, CWA doesn't always play by the rules!
OCS clients should process normalization rules according to the order defined in the location profile. This works fine in MOC. However, CWA reads the rules in the order they were entered into Active Directory according to creation time. Jens also says this bug will be fixed "in a future version of CWA, but until that is available you will have to use work-arounds." I don't know what's involved but it seems a simple fix for a product they're pushing very aggressively since its launch in February. It's also more ammunition for folks saying OCS isn't ready yet. Though I disagree and think OCS R2 can be a good PBX replacement I have to admit this is should have been found and fixed in beta.
