Freepbx configuration -- 2

Job ID: 37230974

Budget: €8 – €20 EUR

I have a VOIP PBX based on Freepbx with 2 extension . I need to do the following configurations:
1) When a call comes in, both phones must ring;
2) If the call is answered from one of the two phones and in the meantime another call comes in, the caller must simply get the busy signal
3) While talking from one of the two telephones it must be possible to make a call from the other, i.e., the one that is not busy.
4) When a call comes in, and no one can answer, after a certain number of rings (8) play message "operator not available try again later".
5) The answering machine should answer only when it is activated with the night and day option with code *280
