[cisco-voip] Time on CCMs and phones..

Wed Sep 20 16:47:23 EDT 2006

Look for a directory c:\program files\cisco\xntp (going on memory here).
You should also see "Network Time Protocol" listed as a service, and it
should be started.  The main configuration file I believe is
C:\WINNT\ntp.conf (a directory listing should find it if that's not the
exact name).  Once edited, restart the time service, and that should correct
the CCM time (if it's 10 minutes off, it will correct it slowly).

hmmm..

I don't see that on my system- either in Services in serviceability or in NT
services in Administrative Tools...

wonder where it gets installed from in 4.01 ??

We've found that the NTPD service (Cisco NTP) that comes with CallManager is
right-on and very reliable.  We use that instead of the Windows time
service.  That would be my recommendation.
