Hi
I am not using a server, I just populated MB 20-57-01, 20-57-02, 20-57-03, 20-57-04 and 20-59-01, 20-59-02 and:
20-59-03: Enable
20-59-04: Enable
20-59-05: Extension number
20-59-07: Enable
20-59-08: Enable
20-59-09: Enable
20-59-10: Enable
20-59-11: Disable
20-59-12: Disable
20-59-13: Enable
20-59-14: Desktset
20-59-15: Desktset
20-59-16: Enable
20-59-17: Disable
20-59-18: Enable
20-59-19: Disable
20-59-20: Disable

In settings of Desktop suite I set up in preference to get both name and number.

My Desktop Suite it's working fine but I have only this issue.

Thanks for reply!
