  5. Since these devices are used in conjunction with FiOS connections, traffic shaping is not necessary. This is due to the fact that the connection is Symmetrical and the speeds in most U.S. markets start at 30x30. However, in the event it is determined to be necessary, the following settings can be entered by the customer or their IT staff.
    1. Advanced > Yes to the warning > QoS > Traffic Shaping.
    2. Click the Add option.
      1. Device: Network (Home/Office). Click Apply.
      2. Use this speed test link to take an average of three speed tests: Telecom Speed Test
      3. Using the averages derived from the speed test on the previous step, set the Tx (upload) and Rx (download) according to the following usage notations for the VoIP devices connected. Maximum: calculate this number: (#-of-phones * 100kbps) + (#-of-fax-adapters * 100kbps) + (50 kbps for 1 VoIP/Soak Test Tool).
  6. For the last step, we need to change the LAN side DNS servers.
    1. My Network > Network Connections
      1. Click on Network (Home/Office)
      2. Click on Settings.
      3. DNS Server, enter the following
        • Primary DNS Server: 8.8.8.8
        • Secondary DNS Server: 8.8.4.4
