T38G - Softkey autoprovision not working (Remote Phone Book)

[SL2013]

Thanks a lot for your help!
The autoprovision is working now, but I have still one question. How can I access the Remote Phone Book with a softkey. I can access directory but it only contains the local contacts (1. Contacts). How can I add the remote phone book on Directory or add the remote phone book directly by a softkey?
