Using Custom Selection of VIP DID numbers, you can select the DID number assigned to a room when a guest checks in. It also provides buttons on display sets with which you can check in a VIP (the vip-chkin button), view and change XDID and XDIDVIP numbers (the did-view button), and dissociate XDID and XDIDVIP numbers outside of the normal guest check-out procedure (the did-remove button).
