Importance Of Testing VoIP Performance

VoIP phone service has turned into a key tool for businesses. A VoIP connection makes it simple and quick for customers to get in touch with companies, improving customer satisfaction. Poor call quality can seriously hamper team collaboration and the decision-making process of customers. A VoIP test is important to verify that the business will not suffer from poor call quality. The VoIP speed test will further streamline in-house communication alongside outside interaction with clients.

What is a VoIP test?

A VoIP quality test measures the latency and speed of the internet connection. This not only checks its performance but also checks the internet bandwidth’s capacity to support VoIP calls. The more bandwidth an internet connection has, the better the quality of the voice calls. Network bandwidth controls how quickly data transfers and how fast the connection is.

Factors That Affect VoIP Performance

The way devices such as PCs, routers, SIP phones, and servers channel internet traffic is the main determinant factor in the quality of VoIP service. The flow of VoIP traffic is impacted by three key factors.

  1. Provider of VoIP services
  2. Network/router configuration
  3. ISP connection

VoIP connection issues usually start with poor audio quality. This can include jerky, cut-up, and inaudible voice fragments. The root cause of the problems can be identified with a VoIP speed test, traceroute, and ping test.

How To Check The System Before VoIP Testing

The quality of VoIP speed can be measured by.

Upload speed

If the VoIP quality tests show a fast upload speed, it means that the person on the other end of the line can easily hear the operator. The ideal upload speed is three megabits, and anything less will lead to a drop in the call quality.

Download speed

The recommended download speed is three megabits per second, or between 100 and 300 kbps. It helps in figuring out how many calls the network can handle simultaneously and whether an operator can hear the other party.


Jitter is caused by out-of-order data packets. That can also happen if packets are delayed. Voice calls’ quality suffers when such packets are delayed. If the jitter is higher than 15-20 ms, the company needs to upgrade the existing bandwidth.


The total time it takes to send and receive data is known as latency. Call performance can decline as latency increases. Latency must be kept at or below 150 milliseconds.


It’s a good idea to be familiar with the techniques discussed in this article for troubleshooting and optimizing VoIP call quality. These are also short-term solutions to keep the business operation running at pace. Large firms, however, cannot afford to handle VoIP issues haphazardly. In fact, enterprises run the risk of having their entire UC infrastructure compromised if proactive solutions aren’t in place to continuously monitor, diagnose, VoIP test, and pinpoint flaws. Furthermore, it is always important to choose a top-notch VoIP monitoring system for the company, particularly one with a strong reputation and a track record of delivering high-quality customer care services.
