4.3 Quality of Service

The QoS settings ensure packet-optimized transmissions within the network.
Usually, QoS is only supported in large networks. Please deaktivate Layer 2 und Layer 3 in
low-end network that do not support QoS / Vlan.
The QoS settings have to be synchronized with the network administrator.
>Older network components may not be able to read packets with Vlan tag. In these
cases, Layer 2 und Layer 3 have to be set to "Off" using the user interface of the
telephone.
