In addition to the essential network requirements for NUACOM phone systems, certain recommended network configurations can further improve call quality, stability, and overall reliability.

These recommendations are not mandatory, but they can significantly enhance performance, especially in busy network environments.

Quality of Service (QoS) for Voice Traffic

Implementing Quality of Service (QoS) on your local firewall or network switches helps prioritise voice traffic over other types of data.

Why QoS is recommended

Voice calls are sensitive to network conditions. When a network experiences high data usage or limited bandwidth, voice traffic may be delayed or dropped.

Network congestion can result in:

• Choppy or distorted audio

• Delays or lag during calls

• Interrupted or dropped calls

Real-time voice traffic requires a consistent and reliable flow of data packets. QoS helps ensure that voice traffic is prioritised, even when the network is busy.

Implementation notes

• QoS methods vary depending on the firewall, router, or switch in use

• Configuration should be aligned with your existing network setup

• We recommend consulting your IT support or network administrator when implementing QoS rules

Separate VLAN for Hardware Phones

If you are using hardware desk phones with your NUACOM phone system, configuring a dedicated VLAN for voice traffic is recommended.

Benefits of a separate VLAN

• Separates voice traffic from general data traffic

• Improves traffic prioritisation

• Reduces the impact of other network activity on call quality

• Simplifies network troubleshooting

This approach is particularly beneficial in offices with multiple users, shared internet connections, or high data usage.

DSCP Support for Audio Streams

NUACOM desk phones and applications use DSCP (Differentiated Services Code Point) for audio streams.

• DSCP markings allow compatible network equipment to recognise and prioritise voice traffic

• This works in conjunction with QoS and VLAN configurations

• DSCP support depends on your network hardware and configuration
