UC500 CUE Clock Unsync

Dear All,

Is it normal that the clock state is unsync in UC500-CUE?(I have only one at hand).


UC500-CUE# sh clock detail

12:35:41.236 NZST Fri Aug 08 2008

time zone: Pacific/Auckland

clock state: unsync

delta from reference (microsec): -14410

estimated error (microsec): 66869

time resolution (microsec): 1

clock interrupt period (microsec): 10000

time of day (sec): 1218155741

time of day (microsec): 247760


Recently I have a problem of 12-hour time shift in the Voicemail messages. Messages recorded in AM is reported as in PM. NTP on both CME and CUE are correctly synced, but the clock state in CUE shows unsync.

Any reference to sync the clock?

Thanks in advance.

Re: UC500 CUE Clock Unsync

Have you configured an NTP server within unity express?

CME Config


interface Loopback0

description Loopback For UnityExpress

ip address


interface Integrated-Service-Engine1/0

ip unnumbered Loopback0

service-module ip address

service-module ip default-gateway

no keepalive


ntp master

CUE Config

CUE>ntp server prefer

Thanks to the reply.

The NTP is syncronized. The clock shows correct time and date, but the clock state still shows uncrync even after reloading.

Do you suggest a CUE upgrade?
