We use Cisco Call Manager Express on a Cisco 2800 router
OS Description  Cisco Internetwork Operating System  
Cisco IOS (tm) C2800NM
Software Version  12.4(3g) / CME 3.3  

the time on the phones keeps changing back to 10 minutes off. We correct the time in the GUI and its fine for a few hours then changes itself back to 10 minutes off.

Here is the output from the NTP commands

sh NTP status
