Hey guys, thanks for the reply. Unfortunately the problem started happening in about 1 year of the initial install. I guess the Battery could be bad, but why isn't any Telephone data lost?
The KSU was installed without UPS, just Surge Prot. initially, and we added the UPS last year to address this specific problem. If anything, I believe their outtage yesterday was the worse in terms of lost/corrupt data and messages. The VM system always stays online, but with the corrupt data there is no way of knowing what works and what doesn't.
The system is not bonded with a dedicated ground, because some of our worst lightning related system failures have been on bonded systems. But I will try this at this site.
Previous posts state 20052 is stable, do you disagree. Also, previous posts state "don't mess with COS", which we have unfortunately done here and I will put COS back to default and reinitialize.
Thanks again and any other thoughts or experiences would be greatly appreciated, Mike.
