Prevent prefetching of remote phonebook

[dmark]

Hello Travis,

thank you for your answer. I sent you the requested video and additionally
- the Apache access.log when opening the remote phonebook. You can see a bunch of http requests within a few seconds.
- the "http-result-u_41.txt" shows the result of initially calling the remote phonebook for user "41" (parameter "u=41"). It is mainly the XML Menu with three URLs.
- the "http-result-u_41-t_imported.txt" shows the result of calling the "imported Company-wide Phonebook" (Parameters u=41&t=imported). There are the first 15 entries and the URLs for the SoftKeys to refine the search.

The problem is that the Yealink phones immediately start requesting all further HTTP URLs they find in a XML Menu or Directory.

Further Info: I try to implement Yealink support for the (mainly) german open source PBX "Gemeinschaft 3" (https://github.com/amooma/GS3). You can find the remote phonebook implementation for the Snom phones here:
https://github.com/amooma/GS3/blob/maste...nom/pb.php

I try to do something similar for Yealink so the User does not need to care about which phone he/she actually uses.
