I have a UCM 6.x box and installed there the 1.4 Dutch / Netherlands dialplan. When looking at the Dialplan installer it says NLNP installed version 1.4 However when i go to my existing Route Patterns the box of choosing the numbering plan is greyed out. When creating a new route pattern the box is still greyed out. What am i missing to get this dialplan working ? Or was installing this dialplan enough ?
