SNTP Server

The CIC installation process sets the SNTP (Simple Network Time Protocol) service to run on the CIC server. Depending on where CIC is installed, it may require more SNTP configuration.

Note: You can also configure SNTP settings through DHCP. For more information, see "Configure the Time Server (Polycom and IIS)" in the CIC Managed IP Phones Administrator's Guide. These settings are valid for both managed and non-managed phones.

CIC installed on a domain controller Windows Server 2008

No additional SNTP service configuration necessary.

CIC installed on a non-domain controller Windows Server 2008

It's possible that the NTPServer is not enabled. The system is an NTP/SNTP client, but not a server.

Do the following for the SNTP service:

  1. Change a registry entry on the CIC server:

    1. Locate HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpServer and set the value of Enabled to 1.

    2. Open a command window, and type:

      net stop w32time && net start w32time

      Note:
      The NTP/SNTP server-side functionality is not active on non-domain controllers by default.

  2. Supply the address of the SNTP server in the xIC.cfg file.

CIC installed on a non-domain controller Windows Server 2008 system in a domain without a reliable NTP source

Polycom phones do not use this NTP server. A reliable NTP source can be external or direct.

Do the following for the SNTP service:

  1. On the CIC server locate HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config and set the value of AnnounceFlags to 5.

  2. Locate HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpServer and set the value of Enabled to 1.

  3. Open a command window, and type:

    1. net stop w32time && net start w32time

    Note:
    These registry changes makes the time services a trusted authority using the local clock. A system that uses an external NTP server is preferred, but the default configuration is to try to use an external NTP server. If that is not working, these parameters treat the computer clock as a trusted source for computers connecting to this SNTP server.

  4. Supply the address of the SNTP server in the xIC.cfg file.
