SIP 8831 Wrong Time CME

[silvakizir]

We have CME 11.7 with SIP Phones 7811, 7821, 8831, 8845, 8851 and all of the phones have the correct time apart of the 8831.

8831 phone has the Firmware 10-3-1SR3-5 which is the latest.

Does anyone know how can I fix this?

Thank you.

Perform factory reset and let it reinstall the firmware

I did a Factroy Reset but unfortunately it does not erase the Firmware.

I did it with both ways (Mute Button and Apps=>Admin Settings=>Reset Settings=>All) as described bellow.

The phone whatsoever boots up normally like nothing happened and as an active firmware I see the 10-3-1-SR3-5 which is the latest I configured manually in the beginning of the CUCME configuration.

I also changed the command load 8831 10-3-1-SR3-5.sip to load 8831 10-3-1-SR2-2.sip which is the previous firmware in "voice register global" but nothing changed.

Clock still remains wrong in this phone..

Hi all 

this command has made life easy ,, works perfectly 

happy to help

Copy the "TzDataCSV.csv" and "tzupdater.jar  into CME router flash.

2. Configure below commands to make the files available through TFTP.

tftp-server flash:TzDataCSV.csv

    tftp-server flash:tzupdater.jar

3. In "voice register global" configure timezone using below command. Use the timezone names mentioned in .csv file (you can open the file with Excel).

    voice register global

    olsontimezone xxxx/xxxxxx version 2015a

    no create profile

    create profile

    reset

4-voice register pool

Apply-config
