Prevent prefetching of remote phonebook

[dmark]

OK, then I misunderstood you. I thought that 28.81.0.41 was a beta firmware with the new feature included.

My initial question was not a "special request". I am working on support for Yealink IP phones for the (mainly german) Open-Source VoIP-PBX "Gemeinschaft 3" (as mentioned above). I think it would be great if Out-of-the-Box Yealink phones will work with that PBX. Actually you can use Yealink T42G, T46G and T48G with that PBX, but phonebook works completely different compared to other supported phone types. This ist the situation I tried to avoid...
