Configure QoS Setting

Step 1. At the phone adapter configuration utility, choose Network Setup > Application > QoS. The QoS page opens up. It contains the following fields:

• QoS Policy — Choose whether you need the feature to be enabled always or only when there is voice traffic.The possible values are:

– Always On — Click this option if you want to enable QoS at all times.

– On When Phone In Use — Click this option if you want to enable QoS only when there is voice traffic.

• Upstream Bandwidth — Specifies the maximum available upstream bandwidth value provided by the Internet Service Provider. The range is from 64 to 100000 kbps. The default value is 10000 kbps.

Note: Setting this value higher than the available service bandwidth can result in traffic being dropped arbitrarily in the  service provider's network.

Step 2. Click Submit to save the settings.

A status message is displayed confirming that the settings have been saved.
