QoS Recommendations For Voice Network Traffic

Designing a business-grade information network has a lot of moving components that need to be planned for. Though IT is one of those professions that can solve issues simply by throwing money at them, sometimes that is not the best route to take. So, network engineers need to design networks with capacity in mind. One of the methods in which network capacity can be controlled is through QoS (quality of service) rules, and one of the best use cases for implementing QoS rules is for voice communication.

Many businesses utilize VoIP phone systems today, which means that voice traffic is being routed through the business network. Though VoIP systems are rather resilient and use UDP traffic, it's a good practice to ensure that the network has enough capacity to handle that traffic so voice calls don't sound choppy.

Cisco recommends that QoS rules for voice traffic range from 17 to 106kbps of network bandwidth should be available per telephony device for clear and smooth voice communication. The exact amount depends on the codec used for the VoIP network. Lossy codecs demand less network bandwidth while other lossless codecs will require more.
