    3CX softphone on Android over cell network, cannot register through tunnel. Tunnel shows connecting, then registering, then times out.

    I have port 5090 TCP and UDP static mapped. The request is allowed through the firewall, I can see it go through.

    Firewall checks all green.
    Windows firewall is off
    Proxy tunnel service started.
    Also, still getting these, not sure if relevant.
    STUN request to STUN server has timed out; used Transport:
    No other references in the server activity log to the tunnel connecting or the phone registering.

    FYI Direct SIP works fine. All other pbx functions working fine.

    It almost sounds as if the settings for the tunnel (in the Android device) are not "pointing" to the correct IP. Or there is something amiss with your port forwarding.

    You say it doesn't work over the cell network, have you tried, using wifi?
