Time Synchronization issue on CUCM with NTP Server (Cisco Router)

[jahanzaib amin]

Hello Experts,

We need your suggestion to configure Cisco 3800 Router as NTP Server and Syn with Cisco Call Manager to show correct time order on Cisco IP Phones.

There was a NTP Server before which is remove now but IP Phones are showing 30 min off from the Actual time.

We did Cisco 3800 as NTP server and added in CUCM as NTP Server but still time is showing different on Cisco IP Phones.

Please assist.

Thanks,
