Re: Time is uncorrect on IPhone

do you have any IOS router that you can configure as NTP Server and get your CUCM sync with it.

Otherwise, you can sync your cucm to any other type of NTP server or even external server.

thanks

Re: Time is uncorrect on IPhone

Hi Al-kaff,

NTP Servers

Ensure that external NTP server is stratum 9 or higher (1-9). To add, delete, or modify an external NTP server, follow this procedure:

Note You can only configure the NTP server settings on the first node or publisher.

Procedure

Step 1 From the Cisco Unified Communications Operating System Administration window, navigate to Settings>NTP Servers.

The NTP Server Settings window displays.

Step 2 You can add, delete, or modify an NTP server:

•To delete an NTP server, check the check box in front of the appropriate server and click Delete.

•To add an NTP server, click Add, enter the hostname or IP address, and then click Save.

•To modify an NTP server, click the IP address, modify the hostname or IP address, and then click Save.

Note Any change that you make to the NTP servers can take up to 5 minutes to complete. Whenever you make any change to the NTP servers, you must refresh the window to display the correct status.

Step 3 To refresh the NTP Server Settings window and display the correct status, choose Settings>NTP.

Note After deleting, modifying, or adding the NTP server, you must restart all other nodes in the cluster for the changes to take affect.
