CUCM NTP - what will happen?

I just realized that the NTP server our CUCM cluster is pointing to was decomissioned about 8 months ago (it was a 2003 Windows server box).  Somehow our phones have maintained accurate time???

I need to update the NTP server and I think I found where to do it, though I want to make sure its not going to have adverse effects on the system and phones?

Any help?

CUCM 7.1.3b

thanks

You can change the NTP server on the OS admin pages

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/cucos/7_1_2/cucos/iptpch4.html#wp1042131

This will propogate a time change on your phones.

If your existing server reference is offline your CUCM will be using

the onboard system clock from the physical server

You can check your current ntp status by using the

Putty SSH console

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/cli_ref/7_1_2/cli_ref_712.html#wp42375

utils ntp status

and change here to with

utils ntp configure A.B.C.D

No noticeable affect
