Cisco 8841 phone firmware is not upgrading

[Yenosh]

Hi 

We have around 30 phones in office , 10 of the phones are registered CUCM but remaining phones are not registered. It seems phones are not getting upgraded to sip88xx.14-0-1-0201-171 from sip88xx.12. Verified VLAN and IP address range everything is correct. Factory reset did not work.

do we need to update to any intermediate firmware version?

[Roger Kallberg]

AFAIK there should be no need to use an intermediate version for this update. Have you installed the new version on ALL the nodes in your cluster and restarted TFTP service on any node running it afterwards?

Hi Roger

I have verified it is installed on all nodes. I am planning to delete CTL files as these phones are taken from another site.

If still not working, can we collect pcaps

[Roger Kallberg]

I thought you said that you did a factory reset and it did not help? Doing that would remove any CTL and ITL on the phone.

Could you please verify the below points.

• For registration issue, From the phone settings check the status messages.
• For registration issue, Have your properly did a factory reset of phones
• If you are registering  the phone manually,  have you configured these devices with extensions ?
• If not manually, have you enable auto registration.
• Before  firmware upgrade, read the release notes of firmware 14.x. 
• Did you uploaded the firmwares to all nodes
• On device default page for 8841, is it showing the right firmware version ?

Hi , 

I have verified firmware is not on all nodes, its only on pub. Is it necessary to upload on all nodes

Best Regards,

Yenosh

[Roger Kallberg]

Yes. Any firmware COP file should be installed on all nodes in your cluster. That holds true for most types of COP files.

If you're on CM 12, or newer, I'd recommend you to use the cluster upgrade option to install the firmware COP file, if not PCD would be the preferred option to use.

Thanks roger,

I will try to get it done and update here

[Nithin Eluvathingal]

You need the firmware on all nodes. Upload the firmware and see if the phone upgrades.

Hi @Nithin Eluvathingal ,

Can you please provide the reason why it should be on all nodes, I can se in my environment firmware is only uploaded on pub and TFTP1 and TFTP2.

All the phones which are belongs to same location are upgraded successfully, if possible please let me know the reason because i need to submit the justification to upload on all nodes.

[Roger Kallberg]

It is clearly stated so in the read me instructions for the phone firmware files.

Aside from what others have suggested, confirm that there is no "Phone Load Name" assigned to the devices that will not upgrade.  You can find that parameter on the initial device>phone page.  It should be blank, if there is a specific load name in that field, the phone will remain using that load despite your device default load configuration.

A quick way to check to confirm that the firmware you want is loaded on each of your call manager applications is to CLI to them and use the command show version active.
