    Hello,
    I have an ASUS RT-AC3100 router on ASUSwrt Merlin, and something seems to be preventing my iPhone from using Wi-Fi Calling.
    When on any other network, it works fine, but on my network, the "Wi-Fi Calling" carrier signal shows up only for a second, as if the VPN tunnel is terminated.
    I know for sure my network is the problem because I have a personal and a work iPhone on different carriers and the exact same issue is happening.
    My ISP is Bell Fibre (Toronto), and it is connecting using PPPoE.
    Things I have tried:
    - Disabling Firewall on router (so all ports including 500 and 4500 are open)
    - Enabling VPN passthrough on router (including IPSec)
    - Changing DNS on router
    - Enabling IGMP snooping

    Talk to Merlin about it, there might be a bug in his firmware.
    Also try Asus OEM firmware as well.
