Thanks for the responses. Here's some more information. These are working extensions that only have a "display name" the last name and first name field are blank I know at one time they were there as I set this up myself as this was a brand new site about a year ago. When I go into an entry with this issue the form just thinks particularly the voicemail tab and won't allow me to open it. With this particular site I have this issue and a synching issue. Some of the numbers that won't sync only have a directory name and some have a directory name and last/first name. I"m at 6.0 SP1 across the board I've tried all the tshooting steps in the help guide. I"m curios if anyone knows why in the SDS Distribution Errors form that my "force change" button is grayed out I have full rights. I know deleting the number and readding it will probably work as I've done this in the past but with this many extensions I figured I could get to the root cause.
Thanks,
