Search in Remote Phone Book

[SL2013]

We use T38G phones and we want to search in the Remote Phone Book. In our configuration file we have the following line:

super_search.url = http://0.0.0.0/favorite_setting.xml

Favorite_setting.xml contains the following data:

Code:

<root_favorite_set>
<item id_name="localdirectory" display_name="Local Directory" priority="1" enable="1" />
<item id_name="history" display_name="History" priority="2" enable="0" />
<item id_name="networkcalllog" display_name="Network CallLog" priority="3" enable="0" />
<item id_name="remotedirectory" display_name="Remote Phone Book" priority="4" enable="0" />
<item id_name="ldap" display_name="LDAP" priority="5" enable="0" />
<item id_name="broadsoftdirectory" display_name="Broadsoft Directory" priority="6" enable="0" />
</root_favorite_set>

When we touch a button in the Remote Phone Book we get the message: 'The URL is empty!'

How can we solve this problem? It's really important to search in the Remote Phone Book (it contains many records)
