T48G v73.0.50 - "%NULL%" showing for values

We have updated several of our T48G phones to the new v35.73.0.50 firmware. After the upgrade runs we find that many parameters that had blank values, now show as "%NULL%".

This is especially annoying for values that are actually shown on the display. If you have a BLF for x101 but don't put a LABEL on it you get "%NULL%".

We also program several line keys on our phones... so that if Line 1 is extension 101, it would actually be on LineKey.1, LineKey.2 & LineKey.3... both buttons 2 & 3 now display as "%NULL%". Prior to the upgrade, they showed the extension number, 101.

Is this a known issue? I will upload a screen capture from the Web GUI showing the DSS Keys with "%NULL%".

I do understand that %NULL% or !NULL! are intended for DEFAULT values in auto-config. But I've never seen them show in the GUI or on the LCD before.

Thanks

Hello
I have tested it in my side,it can work well .
If you configure the value with %NULL% or !NULL! will default the parameter to default value .
But if you configure it with "%NULL%" means you want to configure the parameter with the value "%NULL%".
so if check if your provisioning file used "%NULL%", if yes, please change it with %NULL% , delete the quotes.

The correct setting :
linekey.2.line = 1
linekey.2.value = 123
linekey.2.pickup_value = 124
linekey.2.type = 16
linekey.2.xml_phonebook =
linekey.2.label = %NULL%

Incorrect setting.
linekey.3.line = 1
linekey.3.value = 1233
linekey.3.pickup_value = 1243
linekey.3.type = 16
linekey.3.xml_phonebook =
linekey.3.label = "%NULL%"
please check and let us know if any question.
Best Regards!

Are you sure you are using the same firmware? We didn't configure anything originally... just did an upgrade.

We have tried:
linekey.3.label =

and we have tried:
linekey.3.label = %NULL%

and we have tried:
linekey.3.label = !NULL!

All three combinations produce "%NULL%" in the Label field... as you can see in my previously attached screenshot.

OK, follow up....

You are testing with Linekey.3.type=16 and linekey.3.pickup_value = 1234

Try testing:
Linekey.3.type=16
linekey.3.pickup_value =

Then try testing:
Linekey.2.type=15
linekey.2.label =

Yes, I tested the version 35.73.0.50.
please send your config.bin file and auto provisioning file that we can try to test it in my side .

below is my test steps :
1. phone version 35.72.0.30,auto provisioning below syntax.

linekey.2.line = 1
linekey.2.value = 123
linekey.2.pickup_value = 124
linekey.2.type = 16
linekey.2.xml_phonebook =
linekey.2.label = %NULL%

inekey.3.line = 1
linekey.3.value = 1233
linekey.3.pickup_value = 1243
linekey.3.type = 16
linekey.3.xml_phonebook =
linekey.3.label = "%NULL%"

2. in the DSS key of the web UI, you can see blank in the label option for both linekey2 and 3 but from the phone UI, you will find the linekey 3 label is "%NULL%" while the linekey2 label is 123.

3. Then I upgrade to the version 35.73.0.50, both web UI and phone UI show like below,
the lable of linekey2 is 123 while the linekey3 label is "%NULL%".

4. then I try the sytnax you mentioned :
Linekey.3.type=16
linekey.3.pickup_value =

Then try testing:
Linekey.2.type=15
linekey.2.label =

both web UI and phone UI show like below,
the lable of linekey2 is 123 while the linekey3 label is "%NULL%"

in this case, would you please send us your config.bin file , auto provisioning file that we can try to check in our side ? you can send them to support@yealink.com
Best Regards!
