1- By this documentation https://wiki.asterisk.org/wiki/display/AST/Asterisk+Call+Files
Could someone explain me what exactly the meaning of this file and what circonstance should I have to use it ?
2- How to configure the dialplan and then the users accept only calls in hours 08:00 to 21:00 ifelse playback (message)
The same, when the call is coming on bank holiday, playback (message) directly
Thanks you so much
