[cisco-voip] Testing phone firmware updates prior to rollout.

[Ryan Ratliff]

This is correct, simply starting the TFTP service (or restarting it)  
won't trigger the phones to download new firmware.  While the device  
defaults page points to the new firmware and after the TFTP service  
restart any phones that happen to boot will get the new firmware.

If you are installing new firmware in order to test in on a few phones  
the order should be:
1. write down current device defaults value for the phone model you  
are installing
2. install firmware via .cop file on the TFTP server
3. write down new device defaults value and change it back to the  
value from step 1
4. restart TFTP service
5. update device page of the phone(s) you want to get the new load,  
reset the phone

Now, I'm not the guy to gainsay TAC or hardly anyone on these subjects,
but restarting the tftp service, I believe, only makes the new files
available to the tftp service.  I don't think a tftp restart entails a
system wide comparison of phone loads and sends new ones to phones which
have old ones.  It's more the phone as it boots up compares its load
with the pub and if different from the Default Load, upgrades itself via
tftp.  Also I'm on ver 6.1, not 7.  But hopefully someone else will
chime in who really knows.

I'm pretty sure I did do a tftp restart after the new load install and
before editing the Device Defaults.

Thanks

Jeff,

What TAC is telling me is that I have to bounce the tftp server on the
Publisher.  Do you remember having to do that step as well?

I've not run ver 7, but in version 6.1 anyway I did this:

In the Device Defaults page, I noted the Load Information for the phone
model I wanted to try with a new phone load.

Installed the new phone load.

Back on the Device Defaults page, the Load Information field for the
phone in question was changed to reflect the new load.  I edited the
field to put it back to the original phone load but also noted what the
new phone load name was.

Finally, on the phone(s) I wanted to test the new phone load, in the
device config there is a field in which you can specify the load you
want to use for that particular phone.  In there I entered the new phone
load name and then restarted the phone.

That worked for me in ver 6.1; maybe it will work similarly in ver 7?

Thanks
jeff

Can anyone share a method for testing phone firmware on a limited set of
phones?

I've installed a TAC recommended firmware update in CUCM 7.0 per the
readme, but now TAC tells me that once I restart the TFTP service, all
phones in the organization will begin downloading the updated firmware.

Thanks in advance.
