Hi All, Following an upgrade from v14 to v15, our Yealink T46G phones wont provision. Logged in to the phones and the server url points to: https://192.168.17.1:5000/provisioning/03xmprud5o After the upgrade the default port seems to be 5001, so changed the url to 5001 but it still won't work. Doing a bit of googling suggested that this provisioning folder should be in the programdata\3cx folder but I can't see it. I see a "provsubdir" under C:\ProgramData\3CX\Data\Http. Tried https://192.168.17.1:5001/provsubdir as the server url and still nothing following a re-provision. We also have a problem with phonebook not working on the handset itself although this has been a problem since version 14, when you go to 3CX phone book and press update on the handset you get a message "failed to download remote phonebook" The template shows the following: remote_phonebook.data.1.url = %%PROVLINK%%/yealink_phonebook.xml remote_phonebook.data.1.name = 3CX Phonebook But i don't know where the xml file is, or how it is generated. I see you can download to CSV on version 15. The system runs on Server 2012R2, windows firewall turned off. I do apologise for all the questions but only been with the firm 6 months and my previous phone system expience was mitel. Thanks, Stuart.
