The Network Utility provides a snapshot of network settings and diagnostic results. While the test is comprehensive some network settings that affect phone service may not be captured in the test. In the event of issues occurring that are likely related to network configuration, the firewall configuration may still need to be reviewed despite passing the Network Utility test.

Caution-Icon.png 8x8 does not recommend or support the use of the Network Utility while connected to a client VPN. Attempting to run the Network Utility while connected to your client VPN will result in the inability to register the application or contact any of 8x8's servers.
