Hello @Fede M. Fernández

I would recommend using a supported provider where pre-configured templates are included in the PBX to help you with configuration and eliminate any guessing work.
The first step to any attempt to connect to a voip provider is to make sure that the firewall checker of the PBX passes all tests. Then based on the information given to you by your provider you can set the trunk up by navigating to the SiP Trunks tab and adding a new SIP trunk.
