Once your organization has deployed the Zoom Phone Local Survivability service module and configured the Local Survivability service, administrators can simulate a failover to verify the service is working as intended.
This article covers:
Note: Network connectivity to Zoom Cloud from the Zoom Node server can be verified via the Virtual Machine itself.
To test the Local Survivability service module, an internet outage will need to be simulated by disconnecting your internet connection or by creating firewall rules to block access to the Zoom Phone networks. To determine the Zoom Phone network, please reference the Zoom Support article for Network Firewall or Proxy Server Settings and refer to the Zoom Phone section for the IP addresses and port numbers you should block.
The Zoom desktop client and physical phones should detect network loss and connect to the local survivability node. The Zoom desktop clients will show a loss of connection as shown here:
To validate that the Zoom soft clients are registered to the Local Survivability service module, do the following on the Zoom client:
Admins can bypass creating firewall rules to simulate failover by enabling Testing Mode. Testing Mode removes the need to block cloud connectivity from the desktop client and ZPLS module. to enable Testing Mode:
Testing Mode is only active once the ZPLS module has been restarted. Users should log out and log back into the client in order to verify Local Survivability. Testing Mode is restricted to the Desktop client and does not affect physical devices.
