Dears

i have configured cisco phones 7821 to work with 3cx but i have a couple of issues:

1) The Setting button shows the phone directory, i want it to show the settings and the directory button to show the directory.

2) the phone does not shows missed calls

so anyone can help

As these phones are not supported by 3CX, you are on your own to find a solution if exist.
