CM express 7906 time 1 hour behind

Unanswered Question
Apr 21st, 2008

firstly I am aware there is a problem with DST and the firmware required to fix this, but I am still having trouble.

CCM express ver 4.1 I have 2 phone types 7940 (time is correct) and 7906's time is incorrect by 1 hour less. I am using sccp11.8-2.2SR1 as required. I have rebooted,reset but still no luck. the phone says it is using the aforementioned firmware, I have the load command in telephony service, I have the relevant tftp-server commands for the firmware and the files are confirmed to be loaded onto flash, this is driving me mad to say the least. Does anyone have any ideas?

I have this problem too.

Hi David,

Hope all is well with you other than this crazy issue! One thing I did notice (and it hit us as well on CCM) was that 8-2-2SR1 did not actually work :(

CME - DST changes are outlined in this doc;

Field Notice: FN - 62686 - U.S. Daylight Saving Time (DST) Policy Changes Effective March 2007 - Cisco CallManager Express (CCME)

Customers who are using the following Cisco Unified IP phone models:








are required to upgrade to the following phone firmware to display the correct time:

CCME 3.X, 4.0 and 4.0(x) customers need to upgrade the phone load to 8.0(4)SR2.

*** CCME 4.1 and 7931 customers need to upgrade the phone load to 8.2(2)SR2.

There are some other thoughts and ideas in this recent thread as well (Thanks Paolo:)

Hope this helps!

Thanks Rob,

I cannot seem to find a copy of 8.2(2)SR2

on the relevant download section I can only find the SR1 firmware.

having tried all the other suggestions on relevant postings in this forum I was rather hoping I had overlooked something simple.

What makes it worse for me is that I have a Express 4.1 lab at home running on Dynamips and I don't get the time issue when running the said SR1 firmware.

sorry to take up your time, but do you have a link for the SR2 firmware, as I seem to be going around in circles trying to find it.

Hi David,

My sincere appologies for wasting your time, it was 8-2-1 that did not work :( I had a look back through my notes here. That is why you can't find 8-2-2SR2 (my bad!)

So, I don't think that is it.

Did you?

no create cnf-files and create cnf-files

This was really covered nicely by Paul in this thread :)

Hope this helps! Again, sorry for that bad info :)
