[cisco-voip] Time on CCMs and phones..

[Tim Reimers]

hi everyone-

I'm having trouble with drifting time on phones-

My setup -
acsccm1 and acsccm2 (publisher/subscriber on 4.01)
acsunity (Unity 4.x)

Supposedly, acsccm1 and acsccm2 get their time from acsunity
acsunity gets its time from ntp.bellsouth.net
That's the same timeserver my main data network uses.

What's weird is that all three 'sets' of servers vary in their time -
ACSCCM1 and CCM2 usually are not far apart- 15 seconds at most.
But Unity this AM was more than 10 minutes different from the two CCMs
And all the VOIP servers were at least 12 minutes different from my data
timeservers.

No firewalls are blocking timeserver ports- a freeware 'get the time'
utility can use ntp.bellsouth.net and successfully get the time and
display it - on all three servers.
No timezone differences (that would result in whole hours being
different anyhow, not just minute differences)


Why are these servers not keeping time with each other, when both are
looking to ACSUNITY, at the very least, and 
Unity is looking at the same public timeserver that my main DCs are for
my data network?


Here's some w32TM output from the various servers.
