Hi, I setup in 3cx some BLF keys for my SNOM 821 (hotdesking via SBC) - If I look in the webinterface of the phone these BLF-extensions are configured as Extensions and not BLF. - If I change it to BLF via the webinterface it seems to be the same? - There is no green led when the BLF-extension is available. It is red though when it is calling. - Why is there no text of this BLF extension on the display?? - And, how can I reach the other BLF-keys, as for now I can only access to two of them?? First button is the hotdesk logoff key. and the 4th is the line key.
