I upgraded CCM5.0.4 to CCM5.1. It just works well after switching version. The only problem is that the phone time is one hour back. I check the Cisco.com there is only a DST Upgrade for 5.0.4, but I cannot find one for CCM5.1. Now I altertively set the correct time on CCM server and reset IP phones. The time display is correct after resetting.
I'd like to know if there is a DST Upgrade for 5.1? Does somebody know the link to download it? Or just setting time on server and resetting phones is OK?
