Cisco 9971 Backlight refuses to go out?

Hello

We have a 9971 SIP phone which is registered to a 9.5 CME Voice Gateway.

The phone works fine but the backlight refuses to go out.

I checked the XML file and it says the following:

<backlightOnTime>07:30</backlightOnTime>

<backlightOnDuration>10:00</backlightOnDuration>

<backlightIdleTimeout>00:01</backlightIdleTimeout>

<webAccess>0</webAccess>

<daysbacklightnotactive>1,2,3,4,5,6,7</daysbacklightnotactive>

The backlight should only come on when the handset is lifted and then go out 60 seconds after its replaced.

All the rest of the phones are workig fine but the 9971 model is not. The backlight stays on permanently.

Could it just be designed like this?

Thanks

Hi DA,

Here is a clip from my response to this question on a previous post;

I think it's the way that this functionality works It's not what you would expect;

Backlight Idle Timeout

Length of time that the phone is idle before the backlight turns off. Applies   only when the backlight was off as scheduled and was turned on by an   end-user (by pressing a button on the phone or lifting the handset).

#

Enter the value in this field in the format hours:minutes.

#

For   example, to turn the backlight off when the phone is idle for 1 hour   and 30 minutes after an end-user turns the backlight on, enter 1:30.

#

The default value is 0:30.

So, if you are testing this during the 10 hours a day that are set as active it's working as designed.

Cheers!

Hi Rob

Thanks for the prompt response.

That's definitely not what I would expect! Is that for all SIP and/or SCC phones?

This handset is on a vessel in the owners office and he only wants the backlight to come on when the handset is lifted so presumably if I change the backlight to be on at 00:00 and to be on for 00:01, i.e one minute. Then the backlight should always be in an 'off' state so the 60 second timeout will kick in and turn it off when the handset is returned?

Thanks

Hi DA,

You are most welcome my friend

Yes, I think that's exactly what you would need to configure

to meet the Owners requirements. It does seem odd to me as well

but I believe this applies to all the 99xx series.

Cheers!

Cisco 9971 Backlight refuses to go out?

Hi Rob

Its 15:09 where I am and I have changed the settings to the following:

00:01

0

1,2,3,4,5,6,7

18:00

00:01

The backlight should come on at 18:00, which means it should be OFF now.

I lifted the handset, put it back down and 5 minutes later its still on!!

Part of me wonders if its actually meant to go off because its the 9971 which is the colour touch screen display, so why would you want the touch screen to go off? Surely you want to be able to use the touchscreen without having to lift the handset?

Thanks

Re: Cisco 9971 Backlight refuses to go out?

Hi Rob

I am hugely appreciative of your help on this one because without it, I would not have been able to sort it!!

Turns out, the 9971 does not have a backlight (so to speak), it has a DISPLAY (posh) and there are a whole set of different (but also the same) settings for this......

Backlight Settings

#conf t

#telephony-service

#service phone daysbacklightnotactive 1,2,3,4,5,6,7 – Backlight to be OFF permanently

#service phone backlightOnTime 07:30 – Backlight to come on at 07:30

#service phone backlightOnDuration 10:00 – Backlight to be on for 10 hours

#service phone backlightIdleTimeout 00:01 – Backlight to go out 1 minute after handset is replaced

As I had the daysbacklightnotactive set to all 7 days, the backlight would be OFF all the time unless someone lits the handset and then (after the handset is replaced) the backlight goes out after 1 minute as set in backlightidletimeout.

If I removed a day from the daysbacklightnotactive, the backlightontime would apply and kick in for the backlight to come on at 07:30 and be on for 10 hours as set in backlightonduration.

As this is a Display phone, the backlight settings above made absolutely no difference but the ones below did.

Display Settings

#conf t

#telephony-service

#service phone displayIdleTimeout 00:01

#service phone displayOnTime 07:30

#service phone displayOnDuration 00:01

#service phone daysDisplayNotActive 1,2,3,4,5,6,7

Same rules apply as above.

The owner of the vessel in my case wanted the backlight to be OFF all the time (even during the day) and only to come on when the handset is lifted, ready to go off 60 seconds after its replaced.

Thanks
