  • Hi James Jac,

    Welcome to post in our forum.

    Regarding this issue, please make sure the port 5061 is open.

    Please also check federation route is enabled in the topology.

    In SFB control panel, check if external access policy is right.

    Moreover, check if you have imported the root CA certificates form your internal Enterprise CA into the Edge server Computer Store.

    For details, please refer to the following document
