Alternative QoS Setup: Cisco Meraki for CrazyCall

The first step in the process of activating QoS on Cisco Meraki is testing your bandwidth. It’s necessary as you’ll need the exact numbers regarding both Download and Upload speed to properly set up QoS.

How to test your bandwidth

Before you run the test, deactivate any traffic shaping or firewall rules that you may have already set. Also, run the test outside of your business hours to get unbiased results.

1. Go to www.speedtest.net and run three separate speed tests one after another. Make sure you save the results of each of the tests.
2. After you’re done with Step #1, highlight only the lowest results for both Download and Upload as we’re going to make use solely of these numbers.

Assuming you got the below results:

Test #1: Download 97Mbps / Upload 79Mbps

Test #2: Download 90Mbps / Upload 84Mbps

Test #3: Download 98Mbps / Upload 76Mbps

To set up your Ubiquiti EdgeRouter Pro we would make use of the 90Mbps for the download and 76Mbps for the upload.

3. Access the Cisco Meraki dashboard

4. For a router: 

• Select Security appliance tab on the left-hand side
• There select Traffic shaping
• Click on the details link on the side of the uplink you use for CrazyCall. Here we use the WAN1 uplink.
• Set the bandwidth according to the speed tests you initially run
• Traffic shaping rules: Add a new shaping rule according to the following one (you’ll find all IP addresses used by CrazyCall in this article)
• Save changes

4. For a Wifi Access Point: 

• Select the Wireless tab on the left-hand side
• There select Firewall & traffic shaping
• Traffic shaping rules: Add a new shaping rule according to the following one (you’ll find all IP addresses used by CrazyCall in this article)
• Save changes

After you’re done with the above your router is all set up to prioritize CrazyCall over other communications which should result in a better call quality!
