Why is a QoS important?
When there is instability in your network some initial information can get lost in transit which results in gaps in the conversation, call drops, and/or degradation in the quality of a call.
In order to avoid that, specific settings can be applied to your router in order to prioritize voice traffic over lower-priority traffic on your network. These settings are most known as QoS (Quality of Service). Keep in mind that even if you have good bandwidth, the stability of your internet network is very important too!
How to set up a QoS
QoS rules can be defined on a router that supports this service. If your router does not support QoS, we recommend the following:
Once you have an adequate router, you can set up QoS rules from your router's interface using the media server IP addresses below. Make sure that you have set all the applicable addresses applied that correspond to your location.
