When there is instability in your network, some call data can be lost in transit. This can result in gaps in the conversation, dropped calls, or a general degradation in call quality.

To reduce this risk, you can apply specific settings on your router to prioritize voice traffic over lower priority traffic on your network. These settings are commonly known as QoS (Quality of Service).

Important: Even if you have good bandwidth, the stability of your internet connection is very important for call quality.

Why QoS is important

Without QoS, all types of traffic are treated equally. When your network is busy, important voice packets may be delayed or dropped, which can cause:

  • Audio gaps

  • Call drops

  • Poor or choppy audio quality

By configuring QoS, you can tell your router to treat voice traffic as a higher priority than other types of traffic, helping to maintain call quality even when the network is under load.

How to set up a QoS

QoS rules can be defined on a router that supports this feature.

If your router does not support QoS, the following models are recommended:

Once you have an adequate router in place, you can set up QoS rules from your router's interface using the media server IP addresses listed in the document below. Make sure you apply all applicable addresses that correspond to your location.
