I use several custom phone templates. In v15, if I make changes and re-provision, the template info on the phone seems to stay cached. I have tried changing the templates for my Yealink T23G's in both the following locations, but the info for the config still stays 'cached'. If I go to Phones "Specific Phone" > Config, I see the old config even after a re-provision. C:\ProgramData\3CX\Instance1\Data\Http\Templates\phones C:\ProgramData\3CX\Instance1\Data\Http\Interface\provisioning\<AuthGenDir> \CustomTemplates\phones On v14, this was not an issue, if I made changes and reprovisioned, the changes would be reflected. There seems to be some sort of caching going on that isn't letting the phones grab the new changes in the template.
