Does your VoIP lives up to all the QoS and QoE expectations?


No matter what service you avail, it is imperative that it meets all of QoS and QoE expectations by all means. QoS and QoE are two service quality measuring standards that establish the credibility of a product/service from users’ point-of-view.

QoS or Quality of Service denotes the measure of overall Idevice/service/product performance. Whereas, QoE or Quality of Experience is associated with the delight or annoyance that a customer gets while using a particular product or service. Both are holistic concepts and enable us to determine the viability of a product and service from a user’s perspective.

What gravity QoS and QoE hold in VoIP? 

Let’s understand this approach with an example. Suppose you have a Brazil phone number with a headquarter location at Sao Paulo (11) city. Here, the connecting link is T3 WAN. Now, you want to be in touch with another remote location office situated in Rio de Janeiro (21) city that is using a T1 WAN link connection.

Will you be able to establish crystal clear connection? 

Of course, not, as there is a link mismatch in the link connection! This mismatch will lead to poor call connectivity, disturbance in the audio, and bad experience.

Now, here is another example for a better understanding of QoS and QoE significance in VoIP.

Suppose your Brazil phone number of Panama (712) city has two different gigabit LAN connections plugged together on a router with T1 WAN interface uplink traffic capability. This is a sheer example of link oversubscription. It leads to poor connectivity on both the LAN connections and as a user, you will be facing a slow browsing issue.

This is where QoS techniques come into the role to enhance QoE

VoIP or Voice over IP networks has become a synonym of hassle-free, cost-effective, and all-inclusive telecommunication. Robust communication was never so easy and dependable as it is with virtual phone system now. While you gear yourself to deploy this cutting-edge technology in your business landscape, paying attention to QoS and QoE is imperative. As the onus of your internal and external business communication is going to be on the shoulders of VoIP, your VoIP must meet QoS and QoE expectations.

VoIP is an internet-based service. Quality and experience issues such as delays, jitter, and packet losses are prevailing in this. The odds of occurring of all these issues swell up by two-fold if you are an enterprise-level business and use a second phone line over a single phone number. This increases the bandwidth burden and degrades the quality of VoIP. While doing VoIP deployment at your workstation, QoE and QoS services are needed to resolve link oversubscription, high bandwidth utilization, data link mismatch, and traffic aggression issues.

How to ensure proper QoS and QoE in VoIP?

For properly optimized QoE and QoS in your VoIP, kindly follow these tips.

• Do proper testing

Several types of testing methods available enable a business to comprehend that its VoIP services and Virtual phone number is as per standard QoS and QoE measures. There is objective (QoS) and subjective ( QoE) methods to this.

In an objective method, you can analyze the quality of network from the network source and use it to determine the quality in objective parameters such as loss of data packets, latency, and jitters.

On the other hand, the subjective method is there to check the QoE in real-time. Its chief aim is to determine the service deliverance or degradation from the users’ point of view. It requires tons of human resources and time to yield correct and dependable results. The Mean Opinion Score (MOS) is another QoE testing tool that determines the quality of media signals, audio, and speech communication over the internet.

• Make sure your VoIP connection is well-tested

As it’s your VoIP connection that you are going to use in the future, make sure that all these QoS and QoE testing are taking place in your work environment at your VoIP connection. Some VoIP service providers claim to do all these testing beforehand. You should not buy all these fake claims and insist on fresh testing.

• Run test twice

For accurate results, you must run the tests twice. One with QoS tagging tuned on and another with QoS tagging turned off. The end comparison with these two results will help you to gain an accurate quality assessment.

• Monitor your network connection regularly

The network is highly erratic and can change its course of action at any point in time. So, if you want to enjoy the persistent quality and excellent service experience, then kindly monitor your network connection regularly and rerun these tests after a regular interval.

So, buy your VoIP from a trusted source, do proper testing, and enjoy high quality and service experience.
