NTP Server ccm 5.1.1

Unanswered Question
Sep 24th, 2008

Hey All,

I'm just pre planning for a day lights saving time change in a voice environment. I'm curious, if the NTP server is set in a call manager cluster, are the end phones time dependent on the NTP servers time? or does a update need to be installed on the ccm?

Many Thanks,


I have this problem too.

Thanks for your reply.

Day lights saving time has changed in au. So my concern is the time wont change on end user phones.

I'm thinking the times from the phones is received from the NTP servers configured in OS configuration?

Need to reset the IP Phones.

For testing reset one phone and check the status

What information in the status of the phone is useful in regards to NTP server from the ccm cluster?
