What is QoS? QoS stands for Quality of Service and in VoIP world, it is the combination of practices and technologies that provide guarantees of acceptable call performance. More specifically, it is a number of settings on your router that will help prioritize data flows.
Imagine a congested highway: the more cars, the less room for flow. If someone is using the bandwidth to download files, this additional load will add up. This additional load takes too much bandwidth, thus the quality of VoIP calls deteriorates, leading to echoes and choppy voice quality. While you can’t increase the amount of bandwidth every time the problem occurs, you can assign priorities to the data flows, recognizing voice traffic as the most important. In essence, this is what QoS is used for.
The negligent use of your VoIP termination or SIP origination, can prevent your business from fully benefiting from these services. To change routers from the default setting of First In/ First Out, you can prioritize your packages. There are three easy ways to use prioritization:
· By TCP/IP Port (Where you assign priorities to a port or a few ports; all traffic that goes through these ports will be marked as high-priority.)
· By device (You type in addresses of the devices used for calls and mark them as high priority)
· By Ethernet Port (Where the traffic going through the Ethernet port of your router will be recognized as the most important)
Although there are equipment which provides for complex QoS settings, it is often better to stick to the basics and use only a few prioritization rules. Conversely, a small router might be unable to serve a more complex telephony system. This is why V1 VoIP recommends that a reseller evaluates the needs of their business customer before purchasing equipment and applying QoS.
