The Zeacom is up to date (5.1 with the latest hotfixes) and I am also using the newest TSP 3rd party driver (5.0).
I also have 2 sites using Zeacom UCB version 6.0 as Beta test sites, both are working flawlessly. I understand version 6.2 is already in the works. By the time NEC approves the 6.0 release, it will be outdated...
I need to plan a trip down under... you need another phone geek down there?
