We run 3CX version 12.0.4 and are using Cetis 3302 voip series Hospitality phones in our 200+ room hotel. From the beginning we have not been able to get the Cetis phones to pull daylight savings changes from the provisioning server, which we have set up as an sntp server. As far as I can tell from the config file it should be looking at that server for sntp information, but they aren't and we have to manually change the Enable Daylight :0 line manually and increment the version number on all 200 + phones....not fun. I have attached one of the config files. Thanks!
