Spa504g xml caller id

Question

Hello,
I have an cisco spa504g voip phone with a configration to connect a xml directory. This works good, but the caller id is not showing and the file with the directory in it is then not called. Is is possible to use this directory to get an caller id?
Example directory file:
<CiscoIPPhoneInput>
<Title>Phonebook</Title>
<Prompt>Prompt text.</Prompt>
<URL>http://192.168.1.74/xml/index.php</URL>
<InputItem>
<DisplayName>Filter</DisplayName>
<QueryStringParam>filter</QueryStringParam>
<InputFlags></InputFlags>
<DefaultValue></DefaultValue>
</InputItem>
</CiscoIPPhoneInput>
index.php file:
<?php
header("Content-type: text/xml");
header("Connection: close");
header("Expires: -1");
?>
<CiscoIPPhoneDirectory>
<Title>Phonebook</Title>
<Prompt>Prompt text.</Prompt>
<DirectoryEntry>
<Name>michel bardelmeijer</Name>
<Telephone>06*********</Telephone>
</DirectoryEntry>
</CiscoIPPhoneDirectory>
Kinds regards,
Michel Bardelmeijer

Hi. what is your firmvare version?
I have SPA504 too, but i can't make the external directory work.
i use string like fnc=xml;url=http://10.1.1.47/book.xml, but getting back error "InvalidXmlURL" on phones console.
