You bet. I can you this one thing in advance. You have to provide Vertical the KSU serial numbers, this is not a code, but the actual number printed on the control unit in order to get the network unlock code. This code also comes with some client software for a pc that provides BLF for all phones for all systems along with some other info. You don't get blf lights for networked phones on the phone itself like you do with the XTS. Nor do you have centralized voice mail, all networked SBXs need to have their own VM card.
