Call Manager time issue

Answered Question
Jan 23rd, 2008
User Badges:

We are running CCM 4.1(3). The time is not synced with the NTP server & is ahead of the domain time by 5 mins. I guess the way to rectify it would be like this -

Run the command from cmd to sync the server with the NTP server. Then reset the Date Time Groups in CCM. Is this correct? What is the command to be applied here?

Hey Abhijit,


It's always something isn't it :)


Synchronize Time Manually with the Time Server Using NTP


Note: This procedure only applies to Cisco CallManager.


Complete these steps in order to synchronize time manually with the Time Server using NTP.


Stop the NetworkTimeProtocol service in the Services control panel.


Synchronize the clock by using one of these commands from a command prompt:


In order to synchronize with a remote Time Server:


ntpdate x.x.x.x


Where x.x.x.x is the IP address of the Time Server.


In order to synchronize with a Broadcast router:


ntpdate x.x.x.x


Where x.x.x.x is the IP address of the Ethernet port of the router.


Restart the NetworkTimeProtocol service in the Services control panel.
