Resetting handset to factory default, is meaning less to the system. Which makes sense, since the phone and Endpoint manager, will automatically configure the phone.
So, I then deleted the 2 config files in /tftpboot/cfg113-states.xml and cfgmacaddess.xml, which did erase some settings, but the phone still displayed the same issues.
I then deleted the extension, 113, from extensions and from Endpoint manager, but it never full disappeared from Endpoint manager.
After that I attempted to recreate the ext, but even though its not listed in Extensions, I could not, since the gui would inform me 113 still assigned to user_name.
Reconfigured phone with new extension, which does cause some issues related to business function. But, the phone still displays the same errors, if you attempt to send a call to ext 114, message will state that is not a real extension.
There is someplace in Freepbx, that I’m still leaving a setting or config file that retains the setting. Don’t know how to remove any reference from Endpoint manager. Which seems to retain a record of sorts.
