Configure Your Unifi Firewall for VoIP

Create a Smart Queue

A Smart Queue option is available with UniFi Security Gateway that prioritizes traffic and minimizes delays when the router/bandwidth becomes overloaded. Activating this option will prioritize all traffic coming in and out of Aircall over other applications traversing the network.

To activate this option…

1. Log into your UniFi controller.
2. Navigate to Settings → Networks.
   
3. In the Networks list, select the WAN network that your VoIP devices will use.
4. In the COMMON SETTINGS section, select Enable Smart Queues.
   

   ✔ Selecting Enable Smart Queues will show the Up Rate and Down Rate fields.

   

    
5. Click PRE-POPULATE to automatically have the Up Rate and Down Rate set to 80%.
6. Click the SAVE button.
   

   ✔ QoS should now be configured on your Security Gateway.

UniFi Access Points and Switches

By default, The UniFi access points and switches will automatically map the DSCP value to a Wi-Fi Multimedia (WMM) priority. Voice is then automatically given highest priority on these devices, so no further changes are needed.
