Source notes citing this source

• The Node console has a network testing tool (option 2) with Common Connectivity, Phone Connectivity and Diagnose Network tests to check cloud reachability. in context
• The ZPLS module accepts no SIP registrations unless its OPTIONS keepalive to the cloud has failed, so a failover test must block both device-to-cloud and module-to-cloud traffic. in context
• A full failover test blocks all connections to the Zoom Phone network, then confirms on the client (Settings > Statistics > Phone tab) that the Register Server IP and port match the ZPLS module, then restores connectivity. in context
• Testing Mode simulates failover without a real outage: after a module restart the module accepts new registrations from desktop clients whose users sign out and back in; IP phones and existing registrations are unaffected. in context
