Implementing a QoS (Quality of Service) is important if you want to make VoIP calls. This allows you to enjoy better call quality and gives your voice connection priority over less important traffic on your network.
What can QoS help with?
- Latency: delay for package delivery
- Jitter: variations in delay of package delivery
- Packet loss: too much traffic causes network packets to be dropped
By implementing a QoS within your LAN, you ensure that your voice data packets (VoIP connection) are given priority over other (less important) traffic. Without QoS, there is no guarantee of good call quality.
Especially for enterprises with 50 devices or more, setting up QoS on the firewall is important. For less than 50 devices, it can certainly help solve existing voice problems but is not necessary.
If you manage your own network you can implement Quality of Service yourself. If you manage your own network/firewall you can ask your external IT partner to set it up.
