Accessing Sipura 3000 FXO port from asterisk

Has anyone any tips on how you can do this please?

I have softphones and normal phone working on Asterisk (still can’t attach to any SIP providers).

But if I ring from outside, although it sounds like it’s ringing there is no ring on phone (or softphones).

I am also interesting in this setup, for receiving and make calls using an ATA.

I would like to use a Sipura 3000 for using its FXO port instead of those
clone X101P cards, that I have heard doesn´t work well.
