On 5.1 a reset of the phone will cause it to update the time. A restart does not change the time. trying to find information about how often the phones update their time from callmanager.
I have had the same problem but found that the CM's have reset there time for the past two days. I have verified that the time has been changed as the Manual workaround stated and that there is not a NTS Server set in the Reg. (this was the problem the first day.) Last night the systems reset there selfs again
Java based phones (7911,7941,7961,7970 etc) should have updated immeadiatly if they have the latest phone firmware (either 8.2.1 or 8.0.4-2) Other phones like 7912,7940 and 7960 will take awhile. The phone updates its time at the completion of each call. You can reset the phones to speed up this process.
Hope this helps!
Hi what is a while? Its been 2 hours almost and I have made and completed a call on my 7940. Still shows 8:34 and the correct time is 9:34. The computer time of my call manager publisher is 9:34 as well as my subscribers... I changed the time on them over two hours ago.... IP phone time is still incorrect...
Can you help??
Well,my phones have started to update themselves. Oddly enough, it is my java based phones that are taking the longest. My older model phones are all updated. I guess I wasn't patient enough.
can you tell me how long it took them? The one sitting in front of me has still not updated and its been about 2 hours or so... I don't have access to any others right now...but Im thinking they are in the same boat...
I have 7940 and 7970 phones and they did not update as they should have. I even went to the CM and Subs (which updated fine) and moved them up a minute, completed a call, and the phones updated a minute. But, the hour digit is still an hour off. I have reset all phones but no luck. Any Ideas?
If I had to guess, I'd say atleast 5 hours. My callmanager's clocks were update via NTP around 2AM (or 3AM with DST). At 8AM they were not updated. I checked again @ 9:30AM and most of them were showing the correct time.
WOW!!! I would not have guessed that long at all... That is ridiculous... I'll wait while and see then... Id say we have about 500 phones or so.
Yup, tried the **#**, I also physically unplugged the phone. No dice on either.
I did as Cisco suggested and reset all my phones, CCM service, and NTP service, but no help.
So far I only have one 7970 that has updated itself.
I assume restarting CCM service will cause a disruption... being a hospital I don't wnat to do anything thats going to cause service interruption if I can at all avoid it...
What CM and OS level are you running? Did you have to make any change for the updates to occur?
...I opened a tac case and Cisco told me to do the following (but it didn't work for me)
1. update device pool time zone to a new time zone, reset devices.
2. Change time zone back to correct, reset phones.
3. Reset CCM and NTP services on all CMs.
im running ccm 3.3.3
OSImage 2000 2.4
OS Service Release 2000-2-5sr4
I have a tac case open, but have not heard back yet... We are a hospital, so it will be very difficult to reset all phones...
Where do you reset the CCM and NTP services?
You can reset the CCM service from the CCM Services website or Windows services control panel, but the NTP service can only be reset via the Windows services control panel (start->run->services.msc)
Press the Services button - then **#** This should work. This funtionality changed with later phone firmware loads.
Hope this helps!
