XML problems: Execute and Input

[Nevox]

Hello,
I use the same template from yealink documentation. Here are some files :

fwd.xml:
<?xml version="1.0" encoding="UTF-8"?>
<YealinkIPPhoneInputScreen type="number"><URL>https://192.168.0.2/yealink/fwd2.xml</URL><InputField><Prompt>Destination:</Prompt><Parameter>num</Parameter><Selection>Selection</Selection><Default/></InputField></YealinkIPPhoneInputScreen>

fwd2.xml:
<?xml version="1.0" encoding="UTF-8"?>
<YealinkIPPhoneExecute><ExecuteItem URI="Led: MEMO4_RED=on"/><ExecuteItem URI="https://192.168.0.2/yealink/fwd3.xml"/></YealinkIPPhoneExecute>

fwd3.xml:
<?xml version="1.0" encoding="UTF-8"?>
<YealinkIPPhoneStatus SessionId="Session" Timeout="0"><Message Size="double" Align="center" Color="black">Poste : 111</Message><Message Size="double" Align="center" Color="red">Transfert : </Message></YealinkIPPhoneStatus>

IMO, the troubles come from:
ExecuteItem URI="http.... : the page is called, but loading remains on screen.
YealinkIPPhoneInputScreen : the form is handled as it has to, but, after commiting results, it comes back to the initial page.

BR,
