Thanks MNDAVE, yes, Vodavi never made me aware but that's ok.
They did recommend 20052 and supplied it to us after the initial problems. They also faxed us the prodeure for "fixing address problems", but we ended up doing initializations each time. A bad load didn't ocuur to me and I will try to get a fresh load of 20052/20053.
We learned on the NEC DS1000/2000 just how important a UPS can be, but generally use the Minuteman Enspire for small Key Systems. I may switch to surge-only outlet for the time being.
Thanks again for the input, Mike.
