I am new to Polycom conference phones we were using Cisco 8831 phones. We are using Cisco CUCM version 10.5.2.1 and the IP 7000 is not displaying the correct time. The date is correct and both date and time are not flashing. The SNTP server is set to north-america.pool.ntp.org and the time zone is GMT -6 Central Time USA and the SNTP Resync period is 86400. These phones were installed two days ago. Thanks,
