Change Exp39 label via XML Browser

[surik]

I have T26P and exp39. I want to change label on exp with this xml:

Code:

<?xml version="1.0" encoding="ISO-8859-1"?>
<YealinkIPPhoneConfiguration Beep="yes">
        <Item>expansion_module.1.key.11.type = 35</Item>
        <Item>expansion_module.1.key.11.line = 1</Item>
        <Item>expansion_module.1.key.11.value = http://192.168.23.16/phone/9118</Item>
        <Item>expansion_module.1.key.11.pickup_value = %NULL%</Item>
        <Item>expansion_module.1.key.11.label = 9118</Item>
</YealinkIPPhoneConfiguration>

This is not works although Remote Control was configured correctly for my PC.
