I have now installed my first (and trial) 3cx system, and it is in the cloud. Behind our router our current installation is all Ubiquiti desk phones, which we used with our previous pbx. They are not one of the auto-provision phones in the 3cx list. Has anyone found a simple way to provision manually phones which are not on the list? while having little experience with 3cx specifically, i have configured my own VOIP systems for some years so am familiar wiht the principles. Any guidance eg pointing me to any documentation for this would be fantastic - i have done various searches to no avail.
