I saw this topic posted here:https://community.freepbx.org/t/phones-keep-changing-network-settings-to-dhcp/56010
No one was able to help, the problem resolved itself without any explanation and the thread descended into chaos. I have the same question. Every once in a while, my DHCP service stops on my server and all my systems lose their addresses. It would be nice to have my phones statically assigned so we can continue to process calls.
I have tried changing to static via the GUI, the phone’s direct interface (menu>network…). The phone reboots and goes back to DHCP. The only thing I can get to work is to change the EPM setting to GUI override (instead of config). Will I lose the rest of my configuration I’ve done through EPM if I go that route?
