Ok, this has been going on since the beginning of the year and its getting very frustrating. I've had a TAC case open this whole time doing whatever it is they want and nothing is helping.
We're currently in Central Time Zone, however, I have to keep our Date/Time Group in the CCM set at Mountain to get the right time to display on the phones. Even though the OS time on the CCM's is correct and set at Central.
So, I've upgraded my call managers to 4.1(3) OS 2000.4.4a, updated the phones loads to the latest SCCP 8.5, verified via SQL Analyzer that the zone is set properly. Still, no go.
I'm out of ideas... Anyone else having this issue?
