Unified communications as a service (UCaaS) became more commonly known…
VLANs (Virtual Local Area Networks) allow you to segment a physical network into virtual networks with different subnet addresses. This will not require purchasing new equipment if your existing switches, access points and/or routers support VLANs and newer hardware generally does that.
Why would you want to separate a network into multiple virtual networks? Well, with VLANs you can separate network traffic and users for specific reasons such as applying different security or policies to different VLANs or groups of users. For VoIP, there are specific benefits in separating data and voice traffic on the network. One benefit is that QoS (Quality of Service) can be applied to the voice traffic via VLAN tagging. VLAN tags are used to provide high priority to voice packets.
Using a VLAN for VoIP also prevents VoIP devices from competing with other traffic on the network, helping to avoid delays in delivering voice packets. A VoIP VLAN also makes it easier to troubleshoot VoIP issues since the VoIP traffic is isolated.
So, if you are having VoIP issues, checking out VLANs is a worthy place to begin the task of troubleshooting.
