5 Causes of Poor VoIP Quality

poor voip quality

If you are using a VoIP phone system, there is a good chance you have experienced poor VoIP quality. The causes of poor VoIP quality calls are easy to diagnose and correct. We will help you identify and work with you to correct these problems. More importantly, these problems should not be ongoing. If your VoIP Service Provider is unable to correct your call quality problems, you need to find a different provider.


  1. The Problem: Jitter

Jitter is a common problem of the connectionless networks or packet switched networks. The information (voice data) is encoded and divided into packets that are transferred over the network and dispatched at their destination. Each packet can travel by a different path from the sender to the receiver. When packets arrive at their intended destination in a different order then they were originally sent, the result is a call with poor or scrambled audio. Our solution is to implement jitter buffers.


  1. The Problem: Latency

VoIP delay or latency is characterized as the amount of time it takes for speech to exit the speaker’s mouth and reach the listener’s ear. Latency can cause delayed or interrupted speech, echo or ‘talk over’ effect.

Latency shouldn’t extend 150-300ms delays, as anything over this level becomes an audible issue for the users on a call. Our solution is to install a VoIP Class router to prioritize VoIP traffic.


  1. The Problem: Poor Internet Connection or Lack of Bandwidth

Most ISPs are designed for web surfing and not VoIP advantages. Transporting voice packets is different and requires an additional set of internet protocols that your ISP may not be providing. Our solution is to install Business Class High Speed Internet.


  1. The Problem: Inadequate Router

This is one of the most common causes of call quality issues. Many small businesses use their internet connection for both voice and data. This is perfectly fine if your router has the ability to prioritize VoIP traffic.

Without a router that is configured for packet prioritization, call quality can be impacted by the other users on your network. For example, if during a call, another user on your network downloads a large file, without packet prioritization, your call quality could be degraded. A VoIP router prevents this from happening by giving priority to voice traffic on your network. We will install to VoIP Class router to increase network performance.


  1. The Problem: Improperly Configured Local Area Network

Many companies do not consider the higher quality demands of VoIP communications. If your company decides to route both voice and data over the same network without properly configuring your network for VoIP traffic, you can expect to have call quality issues. Our solution is to go in and properly configure your network.
