NTP issue with 7932g phone

Hi,

 

I have installed new 7962g phones in the production network. They all are showing wrong time 1 hour ahead of current time. When I connected old 7960 or 7940 ip phone it gave right time. Can not understand what can be wrong. I am using Call Manager 5.x version. Can anyone please help me. Thanks.

What version firmware is running on the 7962G's? Most likely, they're running older firmware, which did not have things taken into account for the recent (past few years) changes to daylight savings. This is a known issue.

Prepare for your VMware VCP6-DCV exam.

Josh Coen and Jason Langer have prepared the latest edition of VCP study guide. Both authors have been working in the IT field for more than a decade, and both hold VMware certifications. This 163-page guide covers all 10 of the exam blueprint sections.

Sorry, I went to sleep after I posted last, because it was quarter after 3am where I am.

Based on the firmware you have listed, it is right in the middle of the day light savings changes that took place in 2007, so depending on where you are, I'd say very likely that this is the issue. Upgrading to newer firmware should resolve it.

A possible work around for the meanwhile is set things to not use daylight savings, and manually adjust the time on CM to reflect the current time.

now 7911 ip phones also showing time 1 hour ahead of normal. What do u think is the problem and what can we do to fix it. All the phones that are showing wrong time are on subscriber not on Publisher. I am using cucm 5.1.3. what can be done to fix it? Do you think restarting subscriber will solve this issue? Thanks.

Now, for upgrading the phones, it is pretty simple for the most part. You just need a TFTP server, and the files you got from cisco.

If you're using the built in TFTP server on a cisco router, then you need to extract the files from the archive you downloaded from cisco (likely that it was a zip file) to the storage for the router (this most often is a compact flash card). Once they're on the flash, you'll need to tell the router that these files are needed to be served by the TFTP server. For that, log into the router, via console, telnet, or ssh and try the following:
Router> en
Router# conf t
Router# tftp-server flash:filenameoffirmwarefile.bin

Open in new window


Just keep repeating that for each of the files from the archive. If you miss anything, then as far as the phone is concerned, it doesn't exist. Once you're done, run "exit" to drop out of configure mode, hit "write" if you're happy with the changes (make sure all is working first), and "exit" once more.

If you have a dedicated TFTP server, things can vary a bit between programs, but you just need to extract the files from the firmware pack into the directory that the TFTP server uses for files that are safe to transfer. For instance, I often use tftpd-hpa, and it defaults to /var/lib/tftpboot/ on my linux machines. Without knowing what you use, then I cannot say exactly where it could be.

If you do not have a TFTP server at all, I'd recommend using the built in Cisco one out of sheer simplicity. You shouldn't have a big need to do tons of phones, so it would work fine, and you don't have to mess with DHCP or anything.

For the CP7911s, what versions are they running? Could be same boat for them. However, given that it appears that this happened on a tuesday, and they are an hour fast, I'd say may not be the case. Check the settings for time on the phones, and on the server itself. If there is another tech trying to work with this issue, maybe they've done something to try and take care of the 62s, and it threw the 11s out of whack. You can give restarting a try, if nothing else, can't hurt things any.

We do not have router....rather we use a physical box for publisher and subscriber.. When I tried to get into publisher using ssh then I get this admin page. On this page I found the command file get tftp file-spec don't know how to use this one... Right now I am using version SCCP42.8-3-2S I want to update it to cmterm-7942_7962-sccp.8-5-3SR1. Will it be compatible and how do i transfer all the files from this Zip to publisher and subscriber. The tftp server address is the address of our publisher.. Thanks.

This is the version of our Call Manager

System version: 5.1.3.8000-4
Administration version: 1.1.0.0-1

Yeah, what ever you use for a file server, the same files will work (and the ones you mentioned are compatible with your phones), so you should be able to give that to publisher. I don't have much experience with Publisher, so I'm sorry I can't help you much help there on how to get your publisher server to distribute the files.

Digging around, in Call Manager, cisco documents show going to Service > Cisco TFTP and then selecting the server will show you the configuration. It should show you where the files are kept, and  you can copy there.

Another site states that the files can be found via the CM Web Portal, or via the Call Manager shell

Another Cisco document, gives the following directions to upload files


Step 1      From the Cisco Unified Communications Operating System Administration window, navigate to Software Upgrades > TFTP File Management.
The TFTP File Management window displays and shows a listing of the current uploaded files. You can filter the file list by using the Find controls.

Step 2      To upload a file, follow this procedure:
a.      Click Upload File.
The Upload File dialog box opens.
b.      To upload a file, click Browse and then choose the file that you want to upload.
c.      To upload the file to a subdirectory of the tftp directory, enter the subdirectory in the Directory field.
d.      To start the upload, click Upload File.
The Status area indicates when the file uploads successfully.
e.      After the file uploads, restart the Cisco TFTP service.

Note      If you plan to upload several files, restart the Cisco TFTP service only once, after you have uploaded all the files.
For information about restarting services, refer to Cisco Unified Serviceability Administration Guide.

Step 3      To delete files, follow this procedure:

a.      Check the check boxes next to the files that you want to delete.
You can also click Select All to select all of the files, or Clear All to clear all selection.
b.      Click Delete Selected.
