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

[Flora_Yealink]

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!
