Good morning! We've installed FusionPBX and created a domain with an "A" redirection . The problem is that we can only connect SIP extensions to the original IP. We tried connecting to the main domain pbx.mydomain.io and it didn't connect. We tried subdomains pbx1.pbx.mydomain.io and it still didn't connect, only to the original IP of the server where FusionPBX is installed. We're sure we have something misconfigured. Can anyone help us?

Thank you very much!
