    I went about setting up a tunnel for my hardphones using the instructions found here:
    https://www.3cx.com/docs/3cx-tunnel-session-border-controller/ - new link

    My system is set up thusly:
    Local IP 3cx:
    Public IP 3cx: 64.50.120.x
    Local IP Hardphone:
    Local IP Proxy Computer:
    Port 5090/TCP forwarded from 64.50.120.x to

    First went about setting up the proxy. To that end, I put the following numbers in the following places:
    IP or FQDN:
    Authentication: 3cx Phone System, 407/407
    On Tunnel:
    Check box "Use Tunnel to Connect."
    Use tunnel of host:
    Remote End of Tunnel: 64.50.120.x
    Tunnel password: xxx

    Click close, then login to new profile.
    I get a display (I'm using desktop mode) of current line status of everybody (like the old Call Assistant used to do). So far, so good, I think. Extension 407 shows up as unregistered, however. I think that perhaps that's the hardphone's trouble, not mine. So I go about setting up my hardphone. I'm using a Linksys SPA-922. My other deployed phone is GS Budgetone 200, but I like the SPA phones better. Here's the settings for that:

    Outbound Proxy: (also tried it with no port number)
    Use Outbound Proxy: Yes
    Use Outbound Proxy in Dialog: Yes
    Display name 407
    User ID, Password, and Auth ID are all set to 407.
    Use Auth ID is set to yes.

    Phone still doesn't show as registered after a reboot however. I can view status with the 3cx VOIP Client, and it shows the tunnel as being connected. But no registration, and nothing shows up in the logs.

    Running a netstat at the command line shows my tunnel connection to my PBX, but just listening on port 5080 for a phone to register, which it never does.

    Any thoughts?
