The 8x8 Network Utility tool will diagnose your network and connectivity to 8x8 servers. Using this will allow us to collect all the test results we need quickly and efficiently. We will simulate phone calls from your location to 8x8 data centers which gives specific measurements indicating network performance.
Step by step guide:
- Download the tool from the 8x8 support center: 8x8 Network Utility v 2.2
- Request an Activation Key from the support team.
- Select all tests and run the tests without repeat option.
- Once all the tests are completed (approximately 30 minutes), under the file menu click File Menu and Save Results.
- We expect the result file in a .txt format sent in as an attachment on an email to email@example.com. We will contact you to help you analyse the result.
To improve the accuracy of your test:
- Ensure PC/LAPTOP is connected through Ethernet cable if agents will use Ethernet, or through Wi-Fi if the agents will use Wi-Fi.
- Run tests from voice VLAN (if applicable).
- Run tests from right circuit, which is used for voice traffic.
- Don’t run test from a Server machine, server machines can be busy performing other tasks or extra security is implemented (desirable).
Actions to take to improve your results:
- Switch to Ethernet if using Wi-Fi.
- Voice traffic Prioritization on Access Point (AP) for Easycontactnow when users are using Wi-Fi.
- Voice traffic Prioritization on /switch/routers/firewalls etc. These are Easycontactnow range of IP addresses for VOIP traffic prioritization. 220.127.116.11/24
- See instructions to disable SIP-ALG if the test indicates it is on. How do I disable SIP-ALG in my router or firewall?
- For customers using external Sip Phones (Such as Polycom or Grandstream): Create separate VLAN for voice traffic.
- Which firewall/router/switches are used in network, make and model?
- What type of circuit is used for WAN connectivity like MPLS, VPN, xDSL etc.?
- What bandwidth circuit is available for VOIP traffic?
Extra Tests to run for more complete diagnostic:
- Run speedtest.net tool or similar to check limits of available bandwidth.
- Run only Media test using tool.Have Repeat option selected for 12 hours. During this test make sure that the PC does not hibernate/sleep/logout and manually stop test.
- Run ping 18.104.22.168 -t and ping 22.214.171.124 -t (UK Customers only) from windows DOS prompt. To stop test press CTRL+C and press right on mouse and SELECT ALL and when all highlighted to White, right click on mouse (data copied automatically), and paste data to notepad. This test needs to run for 12 hours.
