Using DPMA to install phones blocked web access once the P-Series was connected. Not any longer.
Also you could not do a Factory Reset unless on-site and doing it through the phone display.
I just added the other stuff incase people were unaware of these options.
I see…so my P330 & P370 are connected in a non-standard way to freePBX. I somehow managed to use http instead of https. I dont want to open any ports for the certificate management. The phones work ok (the apps too, e.g. visual voicemail), but it seems there is no password requirement for the screenshot. Just tested it.
