First of all you have to set the inside UCM correctly,
you have to correctly neat the ports on your router / firewall, you have to put all the appropriate protections (ACL, whitelist, VPN etc …) then from gs wave amounts the qr code that you will send from UCM via email.
p.s .: I would advise against advising you for security reasons a remote extension in 4G (unless you have static ip or VPN)
