  1. 3cx V20 - Yealink T54W provisions but fails to update config

    Update: I tried reinstalling the PBX server about a half dozen times, switching occasionally between v18 and v20, and noticed in v18 when I would set it up the "legacy" method, and then run LetsEncrypt to update our certs, it would make the PBX webserver totally inaccessible by hostname, as it...
