How to Use 8x8 Network Utility with 8x8 Express

 

Objective 

The 8x8 Network Utility simulates phone calls from your location to 8x8 data centers and gives specific measurements indicating network performance. The tool takes a snapshot of characteristics of your network that affect VoIP call quality, including:

  • DNS service
  • Network path characteristics
  • NAT/Firewall/Router characteristics
  • Packet loss rates
  • Jitter levels (changes in network traffic delivery times)
  • Round trip network delay (latency) between your network and the 8x8 servers
  • Bufferbloat

If the Network Utility finds warnings, please work with 8x8 Technical Support to address them.

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.
