Cisco CME - Cisco 8841 - Backlight Settings

AMDGAMER · ‎02-15-2023

Hi,

Here is my setup:

Call Manager Express: 12.0 on 2911 router

Phones: Cisco 8841/8851 with 12.8.1 firmware

I am trying to set the back light settings so it is active from 7am - 10 pm daily. I've done the following steps, but it is not working.

Configured the following:

telephony-service
service phone daysBacklightNotActive ,
service phone backlightOnTime 07:00
service phone backlightOnDuration 15:00
service phone backlightIdleTimeout 12:00
create cnf-files

voice register global
no create profile
create profile

I have verified the settings are being applied in the XML settings for the phones. I also did a factory reset on the phones after settings were applied. However, it appears the phone is still using the default settings as the screen goes off after 1 hour of inactivity and the screens are turned off on weekends. I'm really at a loss why it doesn't work. Any ideas?

Bump...any ideas?

Have you ever figured this out? I can change all the settings in the config. Mine stay on all day during the week until like 6pm. On the weekends they stay off. It’s like none of those config settings work.

I even tried this;

This should keep the display off every day & it doesn’t work.

Unfortunately, I was never able to resolve this issue and just gave up. Only thing I can think of is a bug in the phone firmware.

Stray_Bullet · ‎08-31-2024

Crap that sucks. Well I appreciate your quick response.

So I think I got it. I added this in the <commonProfile> section instead of the <vendorConfig> section of the phone config. It seems to be working so far... The displays definitely shut off after 5 minutes of waking the phone.

<daysDisplayNotActive>1,2,3,4,5,6,7</daysDisplayNotActive>
<displayOnTime>04:45</displayOnTime>
<displayOnDuration>00:10</displayOnDuration>
<displayIdleTimeout>00:05</displayIdleTimeout>
<displayOnWhenIncomingCall>1</displayOnWhenIncomingCall>
<daysBacklightNotActive>1,2,3,4,5,6,7</daysBacklightNotActive>
<backlightOnTime>04:45</backlightOnTime>
<backlightOnDuration>00:10</backlightOnDuration>
<backlightIdleTimeout>00:05</backlightIdleTimeout>
<backlightOnWhenIncomingCall>1</backlightOnWhenIncomingCall>

Interesting. I assume you manually modified the phone .XML file? My concern would be that when you rebuild the XML files with the below commands that the modified file would get overwritten.

voice register global
no create profile
create profile

Stray_Bullet · ‎09-03-2024

Yes. I modified the xml file. I uploded it with tftp,

copy tftp://10.10.100.12/Phone_Configs/SEP-MY.MAC.ADD.RESS.cnf.xml flash:/its/SEP-MY.MAC.ADD.RESS.cnf.xml

Then Reset phone..

conf t
voice register global
reset

No need to create a new profile. Use command debug tftp events. It will show your phone pulling the new config. Then bam, it works... I had it all, just under the wrong section of the config. Has to be in <commonProfile>. (*** Don't forget to turn off debugging afterwards. no debug tftp events)

Wow So buggy. Today I updated to the newest firmware & had to change it back to the vendorConfig section. Ugh so annoying but it works. lol
