Hi there
Whats the model of phone and CUCM version you are running ? This might be a firmware issue of phones. Try updating firmware to the latest and give a shot
Hope this Helps
Cheers
Rath!

The subscriber(s) should be automatically set to get the time from the publisher. See this output from one of our subscribers for reference.
admin:utils ntp config This node is configured to synchronize with one of the following NTP server(s): usdenextcucm01 admin:utils ntp server list usdenextcucm01
admin:utils ntp status ntpd (pid 10873) is running... remote refid st t when poll reach delay offset jitter ============================================================================== *10.192.21.31 10.192.4.210 2 u 154 1024 377 0.363 -0.219 0.249 synchronised to NTP server (10.192.21.31) at stratum 3 time correct to within 54 ms polling server every 1024 s Current time in UTC is : Tue Mar 15 09:14:17 UTC 2022 Current time in America/Chicago is : Tue Mar 15 04:14:17 CDT 2022

Thank you for your reply ,
When i checked Utils ntp status in Subscriber it gives me :
Utils ntp status
Ntpd (pid 26205) is running…
No association ID's returned
Unsynchronised
time server re-starting
polling server every 8 s
How can i do to resolve this ?
Best regards

Not sure, but as a first step I would recommend you to restart the subscriber node. Then when it comes back check the database replication across your CM system.

The replication between publisher and subscriber is good .

As a matter of fact restart the Publisher as well. Something is off with your system.

The subscriber gets the correct time now after restart cluster , but the unsync message still persist on subscriber . Thank for your help.

Hi,
You probably hit this issue : CSCvs38748
Cisco answer ==> The "/etc/ntp.conf" is empty or corrupted so you need Tac assistance (root access) to update this file with the CUCM IP address.
My alternative answer (without need to ask the TAC) ==> Log into the OS Admin page on the Subscriber. Then go to the page "Settings --> IP --> Publisher" and just click on the "save" button without change anything.
Then, all files in the Subscriber which are based on the Publisher IP address, will be updated. Hence the "/etc/ntp.conf" will be ok.

The issue is for a perticular model or for all of them ? can you make sure that the you have selected proper time zone in Date and time group and applied on the device pool.
As @Ratheesh Kumar mentioned, if there is a firmware upgrade available upgrader the firmware and see if it make a change.

Subscriber should sync with publisher and it should show synchronised and not unsynchronised.
Resolve the NTP issues and I hope the phones will have the right time

I checked the replication it's good , and the publisher is synronised good with NTP and show the correct time , but in the subscriber not .

Are they SIP phones? If so, you will need to add a phone NTP reference to the date/time group that is referenced by the phone's device pool. SCCP phone synch to the publisher automatically. Most SIP phones need a specific phone NTP reference in their DTG.
