NTP unsynchronized error

[voipeee]

Dear All,

I am trying to figure out the NTP unsynchronized issue with the Call manager and Unity. I am using IOS based NTP server. Even though I configured NTP server on the default gateway(2800 router) however, the NTP is still not synchronizing. On the GUI it is showing "NTP unsynchronized" but shows other wise on CLI.

Any response will be appreciated.

HI,

Is the router itself synchronised with an external clock or are you running the router as NTP Master?  You have mentioned router as NTP Server but you have two devices configured.Are you using two routers and do they have the same time? Try configuring the routers to sync to external time source.

Thanks

John

No I have setup this as Master with Stratum 1

I think You missed some configuration on the router. Please check following configuration:
Router(config)#ntp server <NTP server add/IP>

Router(config)#ntp update-calendar
Router(config)#clock timezone EST +4 <Your local TimeZone>

Router(config)#clock summer-time EDT recurring
Router(config)#clock calendar-valid
Router(config)#ntp master 5
