How to Use the 8x8 Network Utility Tool

To use the 8x8 Network Utility tool, open the User Guide in a new browser window. Learn more about the requirements for using the tool here.


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 12 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

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

If the report says OK on all parameters, then the 8x8 Network Monitoring Tool may help identify the cause of network issues.
