Issues with Transfer to Remote Phone Book

[Naum]

Hi we are using t46S phones in most of our sites.
Is it possible to transfer a call to a number selected from a remote phone book (xml phonebook).
At the moment when we like to transfer a call, we press Transfer soft key and there is a option soft key for directory. When this soft key is pressed, only local phone book directory is listed, there is no lisiting of the remote phone book directory.
I went all over the web gui and could not find a way to fix this.

Any help would be appreciated.
