Thank you for directing me to the firmware document.

Do you know if during the upgrade, the default phone load will be used or will it retain the value in the default device list?

Thanks,

Greg

Thanks for the info and the heads up. Now that I know what version to expect, I'll be able to research the best way to get there.

Thanks again.

One more quick question, we currently run firmware v8-3-2S which looks like it needs to be updated to v8-3-3 before going to v9-0-3 or later.

If we we to do the in place upgrade of UCM from 5.1.3 to 7.1.5 would this interim step still be needed?

Thanks,

Greg

Hi Greg,

Yes, this interim step will be required

I have seen a number of instances recently where the CUCM upgrade

failed miserably due to this "Firmware" SNAFU. I would try to get to 8.5.2

at least before the upgrade, but preferably the actual 9.0.x firmware that

was shown in the first link. This has caught many people off-guard during the

upgrade process. The upgrade of CUCM itself will work but the phones fail

and sit spinning with a tftp-Auth error on the display.

Firmware Upgrade Issues for SCCP

NoteFor all SCCP firmware upgrades from firmware release versions earlierthan 8.3(3) to version 8.5(3) or greater, you must first upgrade yourfirmware to version 8.5(2). Once you have upgraded to version 8.5(2),you can upgrade your IP Phone to version 8.5(3) or later.

Hope this helps! Best of luck!

If I may continue on this thread.

I currently have a7.1.3 cluster with phones on sccp version 9.1.1

If I am reading the thread correctly, when i upgrade the cluster to 7.1.5, the phones will actually downrev back to sccp 9.0 (the version contained within the 7.1.5 image)

I would then need to reapply the 9.1.1 sccp firmware.

Am I reading this correct?

Thanks for the sanity check

The phones would down grade if they are restarted. Provided that the upgrade is in place, the phone load will already be available in the TFTP directory. Post install, the default device load will be changed to whatever is contained in the image. You will only have to record the default device settings and re-enter them after the update. Provided that the phones aren't restarted during this time, there will be no affect.

Also, I wanted to mention another coveat relating to the 8.5.2s issue. New phones that are shipped with older firmware can not load the default.term load that is contained in 7.1.5. We had to copy the version from 8.5.2s and over write new.

thanks for the info.  What I have done to speed things up is to downrev my phones tom 9.1, to 9

.0, which is the default firmware installed with 7.1.5   after the cm upgrade, I'll re-apply 9.1 firmware

Also, i see now that 7.1.5 SU4 is releasing soon.  As I am upgrading this friday, I hope its available to download before then.

thanks for your help
