DND via XML notify not working in T48S :-( (works on T41x)

[wecloudit]

Hello,

We push a command via SIP Notify to fetch an XML file and execute it... Fetching etc. all works, but the Phone does not change its DND status.

It works on a freshly factory reset phone but when we press DND on the phone 1 time it breaks...

The XML content:

On:
<?xml version="1.0" encoding="ISO-8859-1"?>
<YealinkIPPhoneConfiguration Beep="yes" >
<Item>features.dnd.enable = 1</Item>
</YealinkIPPhoneConfiguration>


Off:
<?xml version="1.0" encoding="ISO-8859-1"?>
<YealinkIPPhoneConfiguration Beep="yes" >
<Item>features.dnd.enable = 0</Item>
</YealinkIPPhoneConfiguration>

The result:

When it works we see: status changed: update: features.dnd.enable [1]->[0] [Success].

when it is broken we see only: update: features.dnd.enable [Level].

What could be wrong?

DND mode is phone, but custom also does not work...

The same script works perfectly on for exampe a T41U or S etc.
