Just put the SBC on a Windows machine. The installer created Windows firewall rules to open port 5060. I can get the SBC to communicate with the cloud server, but only when I turn off Windows Firewall completely. With it on, phones connecting through the SBC won't connect to the cloud server. I ran logging on the Windows Firewall. When it's turned on, it's blocking port 5353 that seems to be part of the SBC functionality. The installation docs say only 5060 needs to be opened. Amy I missing something? What is port 5353 and why is it affecting me? Thanks!
