    This is with the new SBC 15.5.2607.1 that fixes the certificate expiration issue. I rebooted the server and when the SBC came back up, it reported

     ! Exception: Could not use port
    After that, the SBC service was stopped, or rather, I guess it never started successfully after the reboot.

    There's no reason that 5060 should be in use. I started the SBC and it worked fine. Maybe networking wasn't ready yet? Should the service be dependent on a network service? I'm changing the startup type to "Automatic (Delayed Start)" for now.
