In the Hosted PBX realm, managing VoIP Quality of Service (QoS) ultimately comes down to allocating sufficient bandwidth to VoIP packets at the customer’s router.
Here is an informative article that covers the various methods that organizations can use to ensure that VoIP quality of service meets the customer’s’ needs. It states that:
The most common approach to support VoIP bandwidth is to apply a mix of virtual local area networks, quality of service (QoS) and traffic prioritization across the network to ensure voice traffic is always segregated or given the highest priority between endpoints and call-control platforms.
The article also includes a link to another article – DiffServ QoS model works wonders for VoIP networks – which explains that the three main models used for implementing QoS within a network infrastructure: Best-Effort, Integrated Services (IntServ) and Differentiated Services (DiffServ).
At SkySwitch, we recommend SimpleWan quality of service routers to perform the important function of traffic prioritization. You can learn more about the factors that affect VoIP QoS by downloading our informative whitepaper – Hosted PBX without the Headaches: Quality of Service – on this topic.
