T48G + EXP40 - Cant configure EXP40 using XML Objects

[JohnM72]

Hi

I have a T48G running latest code (35.80.0.125) with an EXP40 connected.
My PBX application pushes config information down to the phone using XML Configuration Objects within SIP Notify Messages.
Config settings for the phone Line Keys are always successful. However Config settings for the EXP40 keys do not work.

For example, to set LineKey 1 on the phone as an XML broswer Key, the following is sent:

<?xml version="1.0" encoding="UTF-8"?>
<IPPhoneConfiguration Beep="no" setType="config">
<Item>linekey.1.type = 27</Item>
<Item>linekey.1.label = DND</Item>
<Item>linekey.1.value = https://192.168.1.197/pbx-1/xhtml.cgi?de...;/Item>
</IPPhoneConfiguration>

This is always successful.

To disable the Key, the following is sent:

<?xml version="1.0" encoding="UTF-8"?>
<IPPhoneConfiguration Beep="no" setType="config">
<Item>linekey.1.type = 0</Item>
</IPPhoneConfiguration>

This is also always successful.

To Set the first key on the EXP40 as an XML browser key, the following is sent:

<?xml version="1.0" encoding="UTF-8"?>
<IPPhoneConfiguration Beep="no" setType="config">
<Item>expansion_module.1.key.1.type = 27</Item>
<Item>expansion_module.1.key.1.label = DND</Item>
<Item>expansion_module.1.key.1.value = https://192.168.1.197/pbx-1/xhtml.cgi?de...;/Item>
</IPPhoneConfiguration>

This occasionally works. Sometimes even the label may be changed but not the value.

To disable the first key on the EXP40, the following is sent:

<?xml version="1.0" encoding="UTF-8"?>
<IPPhoneConfiguration Beep="no" setType="config">
<Item>expansion_module.1.key.1.type = 0</Item>
</IPPhoneConfiguration>

This never works.

I have seen the same results with the EXP40 connected to a T46G.
I can also provide detailed logs from the phone showing that in all cases, the SIP Notify message is correctly received and responded to with an OK.

Any help would be much appreciated!
