Callmanager 7 phone firmware updates not loading to phones

Unanswered Question
Nov 20th, 2008


I just upgraded to callmanager 7.0 and the upgrade went without issues on both our publisher and subscriber servers. The phones all updated to the new phone firmware that is included with 7.0 i.e. for the 7961's they loaded SCCP41.8-4-1S. The problem I am having is that when I doanload and install newer firmware images on the publisher they install without issue onto the callmanager, and also show up under device defaults i.e. SCCP41.8-4-1SR2S for the 7941/7961. However if I reboot the phones they never load the new firmware and even under the firmware load information page in the callmanagers they say that all the phones are running the default firmware. This occurs on all phone models, I.E. 7940/7960, 7931, etc.

What am I missing here? Any thoughts?

I have this problem too.

I'm having the exact same issue upgrading my 7961's on my CUCM 7.0 system...

Hey Jim/Brett,

You may be hitting this bug;

CSCso07551 Bug Details

CTFTP does not update version stamp when phone cop/device pack installed


TFTP does not update version stamp when phone load cop/device packs are


As a result, SIP phones get into a restart loop and SCCP phones do not

upgrade the phone loads.


7.0.0(0.39711.1) UCM


Go the individual phone device page, and save it without changing anything,

and then do a restart or reset.

Unfortunately I just tried that on 2 differant phones and it still didn't work.

For me, this was the fix...

I was attempting to upgrade my 79XX phones to the SCCP41.8-4-1SR10 version and the readme doc was not complete. I states to load this version to the TFTP server and reload phones, when actually you have to load the version to ALL servers in the clusters. I also restarted my TFTP service after all the files were installed. I would try this if you haven't got me going.

As Brett suggested, restart TFTP and your phones should grab the new firmware.

Restarting TFTP did the trick. Thank You everyone.
