How to add remote phonebook to dialing list via provisioning file

[engine411]

2 years ago, I started this thread about using the provisioning file on my 3CX server to have the T46G phones use the 3CX remote phonebook as a source in the dialing list.

My goal then and now.... to be able to view the 3cx phonebook on my T46G and dial by name, i.e. for Jason, I could type 5-2-7, corresponding to J-A-S, and it would display all phonebook entries that matched that.

We've had this working fine in the past. I just upgraded the server to 3CX v14 and need to rebuild my provisioning files, and this old thread doesn't seem to work.

Specifically, when I follow the Yealink directions in that thread and rename common.cfg as y000000000028.cfg and plop that cfg file in the provisioning directory, 3CX overwrites it and the super_search URL is lost.

Yealink, is there a better/newer/different method now? If so, where are directions? Is it better to have the phones periodically copy the remote phonebook to themselves, rather than using the remote phonebook as one source of several sources that are used for each lookup?
Thanks.
