Setting up Quality of Service (QoS) on your Ubiquiti EdgeRouter Pro for Aircall starts with testing your available bandwidth, then applying traffic shaping rules so Aircall traffic is prioritized.

Please follow the steps below and perform tests and changes outside business hours whenever possible.

Step 1: Run bandwidth tests

Before configuring QoS, you need to measure your actual internet bandwidth.

  • Launch your tests outside of your business hours to obtain a proper evaluation of your bandwidth.
  • If you have any traffic shaping or firewall rules already set, deactivate them before launching this test.

Steps:

  1. Go to speedtest.net.
  2. Run three different speed tests in a row.
  3. Note each download and upload result.

Example results:

  • Download 97 Mbps / Upload 79 Mbps
  • Download 90 Mbps / Upload 84 Mbps
  • Download 98 Mbps / Upload 76 Mbps

You will then take into consideration the lowest result, and keep 90 Mbps for Download and 76 Mbps as the Upload speed.

Step 2: Access the EdgeRouter Pro CLI

You can access your Ubiquiti EdgeRouter Pro CLI through the web interface, or using SSH.

Example SSH command:

ssh ubnt@192.168.1.1

Step 3: Apply QoS configuration

You will now create the download and upload QoS policies and apply them to your interfaces.

If you copy and paste the command lines, only use:

  • The first two lines (configure and top)
  • The download policy block
  • The upload policy block
  • The final commit and save commands
