Problem with external call after restore backup

Good morning,
hello, I had to reinstall Freepbx 15 on a Raspberry.luckily I have a backup copy from two days ago, but I have several problems:
-When I receive external calls, I don’t get the calling number on my phone, but I get my phone number

  • I can’t make external calls
  • when I receive external calls I can’t transfer to another extension (before I did it with R41#)

I think it’s the same problem, how could I solve it

thanks
