Configuration of an ATA PAP2

Hello, I’m trying to upload an ATA PAP2T box to my Wazo server, but I can’t find how to do it at all, I put my FQDN etc in the rule profile, however it doesn’t want to upload, if anyone has a solution that would be nice.
Thanks.

Thank you very much but I already followed this link and in fact I’m missing the line: “DHCP Option to Use → Transport protocol to http” and the rest I did before and it doesn’t come up at all, I understand not.
